Run Test Plan

Execute a YAML test plan, run setup commands, health checks, and each test sequentially. Stop on first failure with rich debug output.

Prerequisites

agent-browser skill: Browser tests require the
```
agent-browser:agent-browser
```
skill to be available

Arguments

--plan <path>

: Path to test plan (default:

docs/testing/test-plan.yaml

)

```
--skip-setup
```
: Skip setup commands and health checks (for re-running after failure)

Step 1: Parse Test Plan

Read and validate the test plan:

bash

# Check file exists
ls docs/testing/test-plan.yaml || { echo "Error: Test plan not found"; exit 1; }

# Validate YAML
python3 -c "import yaml; yaml.safe_load(open('docs/testing/test-plan.yaml'))" || { echo "Error: Invalid YAML"; exit 1; }

Extract from the YAML:

```
setup.commands
```
: List of setup commands
```
setup.health_checks
```
: List of URLs to poll
```
tests
```
: Array of test cases

Step 2: Run Setup (unless --skip-setup)

2a. Check Prerequisites

setup.prerequisites

exists, verify each one:

bash

# For each prerequisite in setup.prerequisites
<prerequisite.check> || { echo "Prerequisite not met: <prerequisite.name>"; exit 1; }

2b. Set Environment Variables

setup.env

exists, export each variable. Variables using

${VAR}

syntax should be resolved from the current environment:

bash

# For each key/value in setup.env
export <key>="<value>"

2c. Build

setup.build

exists, execute build commands sequentially:

bash

# For each command in setup.build
<command> || { echo "Build failed: <command>"; exit 1; }

2d. Start Services

setup.services

exists, start long-running processes and wait for health checks:

bash

# For each service in setup.services
nohup <service.command> > .beagle/service-<index>.log 2>&1 &
echo $! > .beagle/service-<index>.pid

For each service with a

health_check

, poll until ready:

bash

timeout=<service.health_check.timeout or 30>
url=<service.health_check.url>
elapsed=0

while [ $elapsed -lt $timeout ]; do
  if curl -s -o /dev/null -w "%{http_code}" "$url" | grep -qE "^(200|301|302)"; then
    echo "✓ Health check passed: $url"
    break
  fi
  sleep 2
  elapsed=$((elapsed + 2))
done

if [ $elapsed -ge $timeout ]; then
  echo "✗ Health check timeout: $url"
  exit 1
fi

2e. Legacy Setup Format

If the plan uses the older flat format (

setup.commands

setup.health_checks

instead of

prerequisites

build

services

), fall back to executing

setup.commands

sequentially and polling

setup.health_checks

as before.

Step 4: Execute Tests Sequentially

For each test in the plan:

4a. Log Test Start

markdown

## Running: TC-XX - <test.name>

Context: <test.context>

4b. Execute Steps

For each step in

test.steps

, determine the step type and execute accordingly:

Shell commands (
run:
steps):

The most common step type. Execute the command via Bash and capture stdout, stderr, and exit code:

bash

# Execute the command, capture output and exit code
<command> 2>&1
echo "EXIT_CODE: $?"

Capture all output for evaluation in step 4c. Shell steps cover:

CLI binary invocations (e.g.,
```
./target/debug/myapp status --all
```
)
Database queries (e.g.,
```
psql "${DATABASE_URL}" -c "SELECT ..."
```
)
File inspection (e.g.,
```
ls -la /path/to/expected/output
```
)
Process lifecycle checks (e.g.,
```
timeout 5 ./myapp 2>&1 || true
```
)
Any other command a human would type in a terminal

curl actions (
action: curl
steps):

bash

curl -X <method> \
  -H "Content-Type: application/json" \
  <additional headers> \
  -d '<body>' \
  "<url>" \
  -o response.json \
  -w "%{http_code}" > status_code.txt

# Capture response for evaluation
cat response.json
cat status_code.txt

agent-browser CLI actions:

Steps starting with

agent-browser

are browser automation commands:

bash

# Navigate
agent-browser open <url>

# Snapshot interactive elements (always do before interacting)
agent-browser snapshot -i

# Interact using refs from snapshot output (@e1, @e2, etc.)
agent-browser fill @<ref> "<value>"
agent-browser click @<ref>

# Wait for conditions
agent-browser wait --url "<pattern>"
agent-browser wait --text "<text>"
agent-browser wait --load networkidle

# Capture evidence
agent-browser screenshot docs/testing/evidence/<test.id>.png

Important: Always run

agent-browser snapshot -i

before interacting with elements to get valid refs, and re-snapshot after navigation or significant DOM changes.

Save screenshots to

docs/testing/evidence/<test.id>.png

4c. Evaluate Result

Using agent reasoning, compare actual outcome against

test.expected

Read the expected behavior description
Compare with actual response/screenshot
Determine PASS or FAIL

4d. On PASS

markdown

✓ TC-XX PASSED: <test.name>

Continue to next test.

4e. On FAIL

Stop immediately. Go to Step 6.

Step 5: On All Tests Pass

markdown

## Test Results: ALL PASSED

| ID | Name | Result |
|----|------|--------|
| TC-01 | <name> | ✓ PASS |
| TC-02 | <name> | ✓ PASS |
| ... | ... | ... |

**Total:** N/N tests passed

### Evidence

Screenshots saved to `docs/testing/evidence/`

### Cleanup

Stopping background services...

Clean up:

bash

# Kill background services
for pidfile in .beagle/service-*.pid .beagle/dev-server.pid; do
  if [ -f "$pidfile" ]; then
    kill $(cat "$pidfile") 2>/dev/null
    rm "$pidfile"
  fi
done

Step 6: On Failure - Generate Debug Prompt

When a test fails, generate rich debug output:

6a. Gather Context

bash

# Get changed files relevant to the failure
git diff --name-only $(git merge-base HEAD origin/main)..HEAD

# Get recent changes in files mentioned in test.context
git diff $(git merge-base HEAD origin/main)..HEAD -- <relevant_files>

6b. Output Debug Report

markdown

## Test Failure: TC-XX - <test.name>

### What Failed

**Test:** <test.name>
**Expected:**
<test.expected>

**Actual:**
<Describe what actually happened - response code, error message, screenshot description>

### Relevant Changes in This PR

<For each file mentioned in test.context or related to the failure:>
- `<file>` (lines X-Y) - <brief description of changes>

### Evidence

<If screenshot exists:>
- Screenshot: `docs/testing/evidence/<test.id>.png`

<If API response:>
- Status code: <code>
- Response body:
```json
<response>

Error Details

<If error message in response or logs:> ``` <error message> ```

Suggested Investigation

<First thing to check based on error type>
<Second thing related to changed files>
<Third thing about environment/setup>

Debug Session Prompt

Copy this to start a new Claude session:

I'm debugging a test failure in branch

<branch>

Test: <test.name> Error: <brief error description>

Relevant files: <List changed files related to this test>

Help me investigate why <specific failure reason>.


### 6c. Preserve Evidence

```bash
# Ensure evidence directory exists
mkdir -p docs/testing/evidence

# Save failure context
cat > docs/testing/evidence/<test.id>-failure.md << 'EOF'
# Failure Report: <test.id>

<Full debug report content>
EOF

6d. Cleanup and Exit

bash

# Kill background services
for pidfile in .beagle/service-*.pid .beagle/dev-server.pid; do
  if [ -f "$pidfile" ]; then
    kill $(cat "$pidfile") 2>/dev/null
    rm "$pidfile"
  fi
done

Test Results Summary Table

Always output a summary table showing progress:

markdown

## Test Results

| ID | Name | Result |
|----|------|--------|
| TC-01 | <name> | ✓ PASS |
| TC-02 | <name> | ✗ FAIL |
| TC-03 | <name> | - SKIP |

**Passed:** 1/3
**Failed:** TC-02

Tests after a failure are marked as SKIP (not executed).

Verification

Before completing:

bash

# Verify evidence directory exists
ls -la docs/testing/evidence/

# List captured evidence
ls docs/testing/evidence/*.png docs/testing/evidence/*.md 2>/dev/null

Verification Checklist:

Setup commands executed successfully
Health checks passed before test execution
Each executed test has recorded result
Evidence captured in
```
docs/testing/evidence/
```
On failure: debug prompt includes expected vs actual
On failure: relevant PR changes listed
Background processes cleaned up

Rules

Stop on first test failure (do not continue to other tests)
Always capture evidence (screenshots, responses)
Include file:line references in debug prompts when possible
Use
```
--skip-setup
```
flag to re-run after fixing issues
Never hardcode secrets - use environment variables
Clean up background processes even on failure
Preserve failure evidence for debugging
Make debug prompts copy-paste ready for new sessions
