Discovering Tests, Tasks and Suites

Installation

The robotcode discover command comes from the optional runner package. If it isn't installed yet, add it:

pip install robotcode[runner]   # or: pip install robotcode[all]

Before you can run, filter, or report on a Robot Framework project you usually want to know what's actually in it: which suites live in which directories, what tags each test carries, which .robot files Robot would even pick up. robotcode discover answers those questions without executing a single test.

It applies the same configuration and profile pipeline that robotcode robot would use to run the project — so what discover reports is exactly what robot would see — and surfaces the result either as a human-readable tree on the terminal or as structured data for scripts, CI pipelines, and editors.

Who this is for:

• Developers opening an unfamiliar project who want a one-shot overview before drilling in.
• CI/CD pipelines that need a stable inventory of tests / tags / files for sharding, reporting dashboards, or build-time validation.
• Editor and IDE integrations — the JSON output is what the RobotCode VS Code extension consumes to build its Test Explorer view.
• AI-driven workflows — coding agents (Claude Code, Cursor, Copilot, …), inventory analyses, test-selection assistants. Letting the agent grep through a tree of .robot files is wasteful; discover returns just the slice the agent asked for (a tag list, a file list, the test tree under one path).
• Test-selection scripts that build -bl/--by-longname lists for robotcode robot — pre-filtering tests for sharded CI matrices, regression sets, or scheduled smoke runs.

Typical things you can do with it:

• get a tree view of every suite, sub-suite, test and task the active profile would discover
• list just the tests (or just the tasks) one per line, with source paths and tags
• list every distinct tag in the project with the tests it tags
• list the source files Robot Framework would even consider parsing
• check the Robot Framework version, Python version and environment the tooling is running under

The seven subcommands share the same configuration, search, and output-format pipeline — once you've learned one the others follow:

Subcommand	Use it when you want to …
all	… see the whole tree (workspace → suite → sub-suite → test/task)
tests	… list tests one per line (typed test)
tasks	… list tasks one per line (typed task, RPA mode)
suites	… list suites only — no per-test rows
tags	… build a tag → [tests] index for triage or dashboards
files	… list every .robot / .resource file Robot would even consider
info	… check the active Robot / Python / RobotCode versions and environment

This guide is split in two:

1. Part 1 — Using the commands walks through every subcommand from the terminal perspective: what it does, what shows up on the screen, and what filters and flags are available.
2. Part 2 — JSON reference documents the structured output for scripts, CI pipelines, and editor integrations — the JSON schema of every subcommand plus jq-based recipes.

For the exhaustive option list see the auto-generated CLI reference.

Quick start

# Workspace tree — every suite, every test, with tags
robotcode discover all

# Flat list of tests, one per line
robotcode discover tests

# Just the test names matching "Login", in the current profile's scope
robotcode discover tests --search Login

# A tag → tests dictionary
robotcode discover tags

# Which source files would Robot even parse?
robotcode discover files

# Active Robot / Python / RobotCode versions + environment
robotcode discover info

If you don't pass paths or filters, discover falls back to the default paths from your active robot.toml profile — the same logic robotcode robot uses.

How discover finds your project

discover runs the same configuration pipeline as robotcode robot:

1. Profile resolution. robot.toml is loaded and combined with any --profile selectors. The resulting profile contributes the default paths (paths = [...]), variables, library paths, and any other Robot Framework settings.
2. Argument layering. Positional ROBOT_OPTIONS_AND_ARGS you pass on the command line are appended after the profile's settings — Robot's normal precedence rules apply. So robotcode discover tests --include smoke ./tests/login picks up the profile's paths unless you give explicit paths (then those win), and adds --include smoke on top of any profile-level includes.
3. Static parsing only. discover never executes a keyword. It walks the suite tree the same way Robot's --dryrun would but stops earlier — at parse time. Library imports, variable files, listeners, and pre-run modifiers are loaded only as far as needed to resolve the tree.

If you want to discover something outside your profile (a one-off file, a specific directory), pass it as a positional argument:

robotcode discover tests path/to/suite.robot
robotcode discover all path/to/dir/ path/to/other/

You can also pass any standard robot argument through — --include, --exclude, --suite, --test, --variable, --pythonpath, … See Robot-native filters below.

Output formats

The default TEXT output is meant for humans reading in a terminal — colourised, paginated. For pipelines, scripts, editor integrations, and AI agents, the global -f/--format flag — set before the subcommand — switches to a stable structured format:

robotcode discover all                       # default: human-readable TEXT
robotcode --format json discover all         # compact JSON, one line
robotcode --format json_indent discover all  # pretty-printed JSON
robotcode --format toml discover all         # TOML

If you only ever look at terminal output, the following sections cover everything you need. For the JSON shape of any subcommand, jump to the JSON reference.

Pager and colour handling is identical to results — see Pager and colour for the details.

all — the full tree

all prints the complete hierarchy the active profile resolves to: the workspace root, every suite and sub-suite below it, and every test or task inside those suites. It's the closest thing to "show me what's in this project".

robotcode discover all
robotcode discover all ./tests/login        # restrict to a path
robotcode discover all --include smoke      # restrict to a tag

Sample output:

Suite: MyProject (tests/)
    Suite: MyProject.Login (tests/login/)
        Test: MyProject.Login.Bad Password (tests/login/test_login.robot:14)
            Tags: regression, smoke
        Test: MyProject.Login.Good Password (tests/login/test_login.robot:22)
            Tags: smoke

Statistics:
  - Suites: 4
  - Suites with tests: 3
  - Tests: 18

Flag reference

Flag	Effect
--tags / --no-tags	Show or hide the Tags: line under each test/task. Default: on.
--full-paths / --no-full-paths	Absolute source paths. Default: relative to cwd.
--search TEXT / --search-regex PATTERN	Prune the tree to tests matching the pattern; surviving tests keep their full ancestor chain. See Search.
-bl NAME / -ebl NAME	Include/exclude tests, tasks or suites by exact long name. See Robot-native filters.
any standard robot flag	--include, --exclude, --suite, --test, --variable, --pythonpath, … passed through to the discovery pipeline.

A diagnostics footer is added to TEXT output when parsing emits warnings or errors (deprecated section headers, duplicate test names, unparseable files). In JSON they land in the diagnostics field — see diagnostics.

tests — flat list of tests

tests collapses the hierarchy: one row per test, with full long name and source location. The natural input for scripts that need a list of test identifiers.

robotcode discover tests
robotcode discover tests --tags                 # add a `Tags: ...` line per test
robotcode discover tests --include smoke        # filter by tag
robotcode discover tests --search "Login"       # substring search
robotcode discover tests path/to/suite.robot    # one suite only

Sample output:

Test: MyProject.Login.Bad Password (tests/login/test_login.robot:14)
Test: MyProject.Login.Good Password (tests/login/test_login.robot:22)
Test: MyProject.Checkout.Empty Cart (tests/checkout/test_checkout.robot:8)

Flag reference

Flag	Effect
--tags / --no-tags	Include a Tags: line per test. Default: off (tests are always one-line in TEXT).
--full-paths / --no-full-paths	Absolute source paths.
--search TEXT / --search-regex PATTERN	Filter by name/source/body/tags.
-bl NAME / -ebl NAME	Long-name include/exclude.
any standard robot flag	Pass-through.

Tasks defined with *** Tasks *** are intentionally not in this list — use tasks for those.

tasks — flat list of tasks

tasks is the RPA twin of tests: one row per task. The TEXT output and flag set mirror tests; only the row label differs (Task: …).

robotcode discover tasks
robotcode discover tasks --tags

In a mixed-mode suite (rare — Robot doesn't recommend it), tests shows the *** Test Cases *** half and tasks shows the *** Tasks *** half. A project where the active robot.toml profile sets rpa = true puts everything under tasks.

suites — flat list of suites

suites lists every suite the active profile resolves, one per line, no per-test detail. Useful when you want to know which suites exist without scrolling past hundreds of tests, or to build a suite-by-suite shard plan for CI.

robotcode discover suites
robotcode discover suites --include smoke    # only suites with a smoke test

Sample output:

MyProject (tests/)
MyProject.Login (tests/login/)
MyProject.Checkout (tests/checkout/)

A suite with no surviving tests after filtering disappears from the list — --include smoke against a suite where nothing is tagged smoke will drop that suite.

tags — tag → tests dictionary

tags builds an index of every distinct tag in the discovered suite tree. The default TEXT output is the tag list alone; --tests and --tasks expand each tag with the tests / tasks it covers.

robotcode discover tags                     # just the tags
robotcode discover tags --tests             # tag → tests, indented
robotcode discover tags -i smoke            # tags appearing in the smoke subset
robotcode discover tags --not-normalized    # keep the original tag spelling

Sample output (--tests):

smoke
    Test: MyProject.Login.Good Password (tests/login/test_login.robot:22)
    Test: MyProject.Login.Bad Password (tests/login/test_login.robot:14)
regression
    Test: MyProject.Login.Bad Password (tests/login/test_login.robot:14)

Flag reference

Flag	Effect
--normalized / --not-normalized	Whether tag keys are normalised (lowercase, no whitespace, no underscore). Default: on. Bug 1 / bug_1 / BUG1 collapse to a single bug1 entry; with --not-normalized the three variants stay separate.
--tests / --no-tests	Add the tests carrying each tag. Default: off.
--tasks / --no-tasks	Add the tasks carrying each tag. Default: off.
--full-paths	Absolute source paths in the expanded child rows.
--search TEXT / --search-regex PATTERN	Filter the underlying test set first; only tags surviving on at least one matching test appear.
-bl / -ebl / any robot flag	Pass-through.

Normalisation in practice

The --normalized default matches Robot Framework's own tag-matching semantics: --include "bug 1" matches tests tagged bug_1 or BUG1. Disable it (--not-normalized) when you want to audit tag hygiene — three distinct dict keys for Bug 1 / bug_1 / BUG1 make accidental variants pop.

files — source files Robot would parse

files lists every .robot and .resource file Robot Framework would even consider loading from the given paths (or the profile's default paths), honouring .gitignore / .robotignore.

robotcode discover files                          # respects profile paths
robotcode discover files ./tests ./resources      # explicit directories
robotcode discover files --search "checkout"      # filename substring filter

Sample output:

tests/login/test_login.robot
tests/login/resources/login_keywords.resource
tests/checkout/test_checkout.robot

Files under directories ignored by .gitignore / .robotignore are excluded automatically. Use this when you need to feed a list of files into another tool (linter, formatter, custom pre-commit hook) and want exactly the set Robot would walk.

Flag reference

Flag	Effect
--full-paths / --no-full-paths	Absolute paths. Default: relative to cwd.
--search TEXT / --search-regex PATTERN	Filter by path/filename substring or regex.

info — environment and version

info reports the versions and platform robotcode is running under — useful for bug reports, CI metadata, and "does this build have the right Robot version" checks.

robotcode discover info
robotcode --format json discover info

TEXT output:

robotVersionString: 7.4.2
robotcodeVersionString: 1.6.0
pythonVersionString: 3.13.2
executable: .venv/bin/python
platform: linux
system: Linux
…

Set ROBOT_OPTIONS, ROBOT_SYSLOG_FILE, ROBOT_SYSLOG_LEVEL or ROBOT_INTERNAL_TRACES and they're echoed back under robotEnv, so you can verify the run environment matches expectations.

Robot-native filters

Every discover subcommand (except info and files) passes through to Robot Framework's own filtering machinery. Anything you'd write on a robot command line works here:

Flag	Effect
-i / --include TAG_PATTERN	Include tests with a matching tag. Supports Robot's AND/OR/NOT syntax and globs (*, ?).
-e / --exclude TAG_PATTERN	Exclude tests with a matching tag.
-s / --suite NAME	Limit to suites whose name matches the glob.
-t / --test NAME	Limit to tests whose name matches the glob (--task is the RPA alias).
-bl / --by-longname NAME	Exact long-name include — no glob expansion.
-ebl / --exclude-by-longname NAME	Exact long-name exclude.
--variable NAME:VALUE, --pythonpath PATH, …	Anything else Robot accepts.

Filters compose — --include smoke --exclude wip means "smoke and not wip".

--by-longname vs --suite / --test

• -s / -t are glob matches.
• -bl / -ebl are exact matches against the full long name. They mirror robotcode robot --by-longname so you can hand the same names to robot and discover.

Use -bl when you have a precise name (often pasted from a failure list or a build log); use -s/-t when you want pattern matching.

Search

--search and --search-regex are mutually exclusive (passing both is a usage error). They prune the discovered tree to tests matching the pattern; surviving tests keep their full ancestor chain so discover all --search Login still shows MyProject → MyProject.Login → Login.Bad Password with sibling suites pruned.

The search applies across:

• the test's name and full long name
• the test's source path
• the test's [Documentation], [Template] and [Timeout]
• the test's tags (Robot's normalisation rules apply)
• every keyword call's name, arguments and assigned variables inside the test body
• FOR/WHILE/IF conditions, VAR/RETURN values, EXCEPT patterns, GROUP names
• any ancestor suite's Documentation or Metadata — a hit on a suite-level field keeps every test underneath it

Flag	Semantics
--search TEXT	Case-insensitive substring match. No metacharacters; [ and * are literal.
--search-regex PATTERN	Python regex, case-sensitive by default. Prefix with (?i) for case-insensitive matching.

Tag targets are matched with normalisation (lowercase, whitespace and underscores ignored), so --search "bug 1" matches tests tagged bug_1, Bug1, or BUG 1. All other targets are matched literally.

robotcode discover tests --search "Login"
robotcode discover all --search-regex 'Login.*(Bad|Good)'
robotcode discover tests --search-regex '(?i)checkout'
robotcode discover tags --search smoke
robotcode discover files --search "_keywords"

Highlighting in the terminal

Matches are highlighted inline in the TEXT output with a yellow background so they're easy to scan. Structured output (JSON/TOML) is unchanged — searching only filters, it doesn't add markup.

Search on tags and files

--search works on these too:

• tags filters the underlying tests first; tag keys whose tests are all dropped disappear from the dictionary. So discover tags --search Login is "what tags are involved in the Login subset".
• files matches the filename / path itself — no body inspection. So discover files --search "_keywords" is "every file whose path contains _keywords".

Invalid patterns

An unparseable regex (e.g. [unclosed) yields a usage error pinpointing where the pattern failed to compile. The command exits non-zero before parsing any suite.

Tips for terminal use

• TEXT output is markdown. On a coloured TTY the markdown is rendered to themed ANSI via rich (and paged if longer than your terminal); on pipes or with --no-color the raw markdown goes through verbatim — paste it into a PR description, a Slack message, or feed it straight to an LLM.
• Quote your globs. --suite "*.Login.*" and --test "Test ?" need quotes so the shell doesn't expand them against the local filesystem first.
• -bl is for exact names, -t is for patterns. When you copy a test long-name out of another tool's output, -bl is usually what you want — no need to escape glob characters.
• Pre-filter before piping into robot. robotcode discover tests --include smoke -f json | jq -r '.items[].longname' gives you a stable list of long names you can hand back to robotcode robot -bl ... for sharded CI runs.
• Parse errors don't stop discovery. Files with syntax errors still appear in the tree; their problems land in the diagnostics field. Pipe through --format json and check .diagnostics for build-time gating.

---

JSON reference

When you set -f json (or -f json_indent for pretty-printed, or -f toml) between robotcode and the subcommand, every discover command emits structured data instead of the terminal-formatted text. This is what CI pipelines, scripts, editor integrations, and AI agents consume.

robotcode --format json discover all
robotcode --format json discover tests --include smoke
robotcode --format json discover tags --tests

Schema rules

A few rules hold across every subcommand:

• camelCase keys. fullName, relSource, needsParseInclude, etc.
• Optional fields are omitted, not null. A null literal never appears. If a field has no value (a test with no tags, a suite with no children), the key is simply absent.
• Empty array ≠ missing field. A field listed in the schema may be [] if the section "exists but is empty"; a field absent entirely means the section wasn't computed for this run. // [] in jq smooths over the difference.
• Stability. Fields are appended over time, never renamed or removed in place. Existing consumers keep working.

TestItem — the common shape

Every subcommand that returns tests/tasks/suites uses the same TestItem schema:

{
  "type": "test",
  "id": "/abs/path/test_login.robot;MyProject.Login.Bad Password;42",
  "name": "Bad Password",
  "longname": "MyProject.Login.Bad Password",
  "lineno": 42,
  "uri": "file:///abs/path/test_login.robot",
  "relSource": "tests/login/test_login.robot",
  "source": "/abs/path/test_login.robot",
  "needsParseInclude": true,
  "tags": ["smoke", "regression"],
  "range": {
    "start": { "line": 41, "character": 0 },
    "end":   { "line": 41, "character": 0 }
  },
  "children": [ /* nested TestItems for type=suite/workspace */ ],
  "description": "Test docstring (when set)",
  "error": "Parse error message (when this item failed to parse)",
  "rpa": false
}

Field notes:

• type is one of "workspace", "suite", "test", "task". workspace is the synthetic root that wraps the actual project directory.
• id is a stable identifier (source;longname;lineno for tests/tasks; source;longname for suites). Editor integrations use this to track which TestItem corresponds to which on-disk artefact across reloads.
• lineno is 1-based; range.start.line / range.end.line are 0-based (LSP convention). Both refer to the same line of source.
• uri is a file:// URI of the source file — same format the Language Server Protocol uses.
• needsParseInclude is true when re-parsing this item requires re-running Robot 6.1+'s include-resolution pass (resource-file Library imports with arguments).
• tags are normalised (Bug 1, bug_1, Bug1 all come through as "bug1") and only present when the item has at least one tag.
• children is the nested-tree field — present on workspace and suite items, absent on test / task.
• range follows the LSP Range shape so editors can highlight the source span.

all / tests / tasks / suites JSON

All four subcommands wrap their items in a ResultItem:

{
  "items": [ /* TestItem(s) */ ],
  "diagnostics": { /* see below */ },
  "filtersApplied": { "search": "Login" }
}

Per subcommand:

• all — items has exactly one entry: the workspace root, whose children is the suite tree.
• tests / tasks — items is a flat list of test / task entries respectively.
• suites — items is a flat list of suite entries (no children — drill into the source files separately if you want per-suite tests).

diagnostics and filtersApplied are both optional and absent when empty / unused.

tags JSON

{
  "tags": {
    "bug1": [ /* TestItems carrying this tag */ ],
    "smoke": [ /* … */ ]
  },
  "filtersApplied": { "include": ["smoke"] }
}

Field notes:

• tags is always an object — possibly empty {} if no tag survived the filter chain.
• Keys are tag names; normalised by default, original spellings preserved with --not-normalized.
• Each value is an array of TestItem objects (the tests / tasks carrying that tag).
• A test with n tags appears in n entries.

files JSON

[
  "tests/login/test_login.robot",
  "tests/login/resources/login_keywords.resource",
  "tests/checkout/test_checkout.robot"
]

files is a plain JSON array of path strings — relative to cwd by default, absolute with --full-paths. No wrapper object, no per-file metadata. If you need richer info, use discover all and walk the tree.

info JSON

{
  "robotVersionString": "7.4.2",
  "robotEnv": {
    "ROBOT_OPTIONS": "--include smoke"
  },
  "robotcodeVersionString": "1.6.0",
  "pythonVersionString": "3.13.2",
  "executable": ".venv/bin/python",
  "machine": "x86_64",
  "processor": "x86_64",
  "platform": "linux",
  "system": "Linux",
  "systemVersion": "#1 SMP …"
}

Field notes:

• robotEnv echoes back any of ROBOT_OPTIONS, ROBOT_SYSLOG_FILE, ROBOT_SYSLOG_LEVEL, ROBOT_INTERNAL_TRACES that were set, and is absent (or {}) when none of them are.

diagnostics

When parsing a file produces a warning or error (deprecated syntax, duplicate test names, unparseable file …), discover all/tests/tasks/suites reports it as an LSP-style diagnostic keyed by the source's file:// URI:

"diagnostics": {
  "file:///abs/path/parse_error.robot": [
    {
      "range": { "start": { "line": 13, "character": 0 },
                 "end":   { "line": 13, "character": 0 } },
      "message": "Singular section headers like '*** Keyword ***' are deprecated. Use plural format like '*** Keywords ***' instead.",
      "severity": 2,
      "code": "discover",
      "source": "robotcode.discover"
    }
  ]
}

Field notes:

• severity follows LSP's enum: 1 = Error, 2 = Warning, 3 = Information, 4 = Hint.
• A file whose parser failed entirely still contributes whatever tests Robot could recover; the unrecoverable parts come through here.
• diagnostics is omitted when nothing fired.

filtersApplied

Every subcommand that accepts search flags includes a filtersApplied field when one was set:

"filtersApplied": {
  "search": "Login"
}

"filtersApplied": {
  "search-regex": "(?i)login"
}

The Robot-native filters (--include, --exclude, --suite, --test, -bl, -ebl) are not echoed here — they're handed straight to Robot Framework's filter pipeline and the effect is visible in the surviving items set.

CI recipes

A grab-bag of jq-based recipes. Pin -f json between robotcode and the subcommand to lock the format.

Build a shard plan

# List of suite long names → fed into a CI matrix
robotcode --format json discover suites \
  | jq -r '.items[].longname'

# Long names of every smoke test
robotcode --format json discover tests --include smoke \
  | jq -r '.items[].longname'

Fail the build on parse errors

robotcode --format json discover all \
  | jq -e '(.diagnostics // {}) | map(.[] | select(.severity == 1)) | length == 0'

List every file the test pipeline would touch

robotcode --format json discover files | jq -r '.[]'

Build a tag report

# tag → count of tests carrying it
robotcode --format json discover tags \
  | jq '.tags | map_values(length)'

# Tags with fewer than 3 tests (candidates for cleanup)
robotcode --format json discover tags \
  | jq '.tags | to_entries | map(select(.value | length < 3)) | from_entries'

Check the Robot version in CI

robotcode --format json discover info | jq -r .robotVersionString

Find tests touched by a specific keyword

# Every test whose body calls `Open Browser`
robotcode --format json discover tests --search "Open Browser" \
  | jq -r '.items[].longname'
