/configure:tests

Check and configure testing frameworks against best practices (Vitest, Jest, pytest, cargo-nextest).

When to Use This Skill

Use this skill when...	Use another approach when...
Setting up testing infrastructure	Just running tests (use `/test:run` skill)
Checking test framework configuration	Tests already properly configured
Migrating to modern test frameworks (Vitest, pytest, nextest)	Writing individual tests (write tests directly)
Validating coverage configuration	Debugging failing tests (check test output)
Ensuring test best practices	Simple project with no testing needed

Context

Package.json: !

find . -maxdepth 1 -name \'package.json\' 2>/dev/null

Pyproject.toml: !

find . -maxdepth 1 -name \'pyproject.toml\' 2>/dev/null

Cargo.toml: !

find . -maxdepth 1 -name \'Cargo.toml\' 2>/dev/null

Test config files: !

find . -maxdepth 1 \( -name 'vitest.config.*' -o -name 'jest.config.*' -o -name 'pytest.ini' -o -name '.nextest.toml' \) 2>/dev/null

Pytest in pyproject: !

grep -c 'tool.pytest' pyproject.toml 2>/dev/null

Test directories: !

find . -maxdepth 2 -type d \( -name 'tests' -o -name '__tests__' -o -name 'test' \) 2>/dev/null

Test scripts in package.json: !

grep -m5 -o '"test[^"]*"' package.json 2>/dev/null

Coverage config: !

grep -l 'coverage' vitest.config.* jest.config.* 2>/dev/null

Project standards: !

head -20 .project-standards.yaml 2>/dev/null

Modern testing stack preferences:

JavaScript/TypeScript: Vitest (preferred) or Jest
Python: pytest with pytest-cov
Rust: cargo-nextest for improved performance

Parameters

Parse these from

$ARGUMENTS

:

Flag	Description
`--check-only`	Report status without offering fixes
`--fix`	Apply all fixes automatically without prompting
`--framework <framework>`	Override framework detection ( `vitest` , `jest` , `pytest` , `nextest` )

Version Checking

CRITICAL: Before flagging outdated versions, verify latest releases:

Vitest: Check vitest.dev or GitHub releases
Jest: Check jestjs.io or npm
pytest: Check pytest.org or PyPI
cargo-nextest: Check nexte.st or GitHub releases

Use WebSearch or WebFetch to verify current versions before reporting outdated frameworks.

Execution

Execute this testing framework compliance check:

Step 1: Detect framework

Identify the project language and existing test framework:

Indicator	Language	Detected Framework
`vitest.config.*`	JavaScript/TypeScript	Vitest
`jest.config.*`	JavaScript/TypeScript	Jest
`pyproject.toml` [tool.pytest]	Python	pytest
`pytest.ini`	Python	pytest
`Cargo.toml`	Rust	cargo test
`.nextest.toml`	Rust	cargo-nextest

If

--framework

flag is provided, use that value instead.

Step 2: Analyze current state

Read the detected framework's configuration and check completeness. For each framework, verify:

Vitest:

Config file exists (
```
vitest.config.ts
```
or
```
.js
```
)
```
globals: true
```
configured for compatibility
```
environment
```
set appropriately (jsdom, happy-dom, node)

Coverage configured with

@vitest/coverage-v8

or

@vitest/coverage-istanbul

Watch mode exclusions configured

Jest:

Config file exists (
```
jest.config.js
```
or
```
.ts
```
)
```
testEnvironment
```
configured
Coverage configuration present
Transform configured for TypeScript/JSX
Module path aliases configured

pytest:

```
pyproject.toml
```
has
```
[tool.pytest.ini_options]
```
section
```
testpaths
```
configured
```
addopts
```
includes useful flags (
```
-v
```
,
```
--strict-markers
```
)
```
markers
```
defined for test categorization
```
pytest-cov
```
installed

cargo-nextest:

```
.nextest.toml
```
exists
Profile configurations (default, ci)
Retry policy configured
Test groups defined if needed

Step 3: Report results

Print a compliance report with:

Detected framework and version
Configuration check results for each item
Test organization (unit/integration/e2e directories)
Package scripts status (test, test:watch, test:coverage)
Overall issue count and recommendations

If

--check-only

, stop here.

Step 4: Apply fixes (if --fix or user confirms)

Install dependencies and create configuration using templates from REFERENCE.md:

Missing config: Create framework config file from template
Missing dependencies: Install required packages
Missing coverage: Add coverage configuration with 80% threshold
Missing scripts: Add test scripts to package.json
Missing test directories: Create standard test directory structure

Step 5: Set up test organization

Create standard test directory structure for the detected language. See directory structure patterns in REFERENCE.md.

Step 6: Configure CI/CD integration

Check for test commands in GitHub Actions workflows. If missing, add CI test commands using the CI templates from REFERENCE.md.

Step 7: Handle migration (if upgrading)

If migrating between frameworks (e.g., Jest to Vitest, unittest to pytest), follow the migration guide in REFERENCE.md.

Step 8: Update standards tracking

Update

.project-standards.yaml

:

yaml

standards_version: "2025.1"
last_configured: "<timestamp>"
components:
  tests: "2025.1"
  tests_framework: "<vitest|jest|pytest|nextest>"
  tests_coverage_threshold: 80
  tests_ci_integrated: true

For detailed configuration templates, migration guides, CI/CD integration examples, and directory structure patterns, see REFERENCE.md.

Agentic Optimizations

Context	Command
Detect test framework	`find . -maxdepth 1 \( -name 'vitest.config.' -o -name 'jest.config.' -o -name 'pytest.ini' \) 2>/dev/null`
Check coverage config	`grep -l 'coverage' package.json pyproject.toml 2>/dev/null`
List test files	`find . \( -path '/tests/' -o -path '/test/' -o -name '.test.' -o -name '.spec.' \) 2>/dev/null \| head -n 10`
Quick compliance check	`/configure:tests --check-only`
Auto-fix configuration	`/configure:tests --fix`

Error Handling

No package.json found: Cannot configure JS/TS tests, skip or error
Conflicting frameworks: Warn about multiple test configs, require manual resolution
Missing dependencies: Offer to install required packages
Invalid config syntax: Report parse error, offer to replace with template
