TeamCity Build Pipeline Monitor

Monitor MikoPBX CI/CD pipeline status, analyze failed tests, and access build artifacts.

What This Skill Does

• Checks build status across the entire pipeline (5 stages)
• Retrieves detailed information about failed tests with stack traces
• Downloads build logs for analysis
• Accesses test artifacts via SSH to build agent
• Provides actionable insights for fixing failures

Pipeline Overview

T2NativeInDocker → IncrementBuild → 172163272img → RestAPITests
                                                 → TESTCASES (UI)

Build Chain:

1. Mikopbx_T2NativeInDocker - Base system build (T2 Linux)
2. Mikopbx_IncrementBuild - MikoPBX distribution build
3. Mikopbx_172163272img - Deploy to test server 172.16.33.72
4. Mikopbx_RestAPITestsOn172163272 - REST API tests (pytest)
5. MIKOPBX_TESTCASES - UI tests (BrowserStack)

Environment Requirements

# Required environment variable
TEAMCITY_TOKEN  # Bearer token for TeamCity API

# SSH access to build agent (for artifacts)
ssh mikoadmin@172.16.33.61

Quick Commands

Check All Build Statuses

TEAMCITY_URL="https://teamcity.miko.ru"

for bt in Mikopbx_T2NativeInDocker Mikopbx_IncrementBuild Mikopbx_172163272img Mikopbx_RestAPITestsOn172163272 MIKOPBX_TESTCASES; do
  echo "=== $bt ==="
  curl -s -H "Authorization: Bearer $TEAMCITY_TOKEN" -H "Accept: application/json" \
    "$TEAMCITY_URL/app/rest/builds?locator=buildType:(id:$bt),branch:develop,count:1&fields=build(id,number,status,state,statusText,finishDate)"
  echo
done

Get Failed Tests Details

BUILD_ID=35133  # Replace with actual build ID

curl -s -H "Authorization: Bearer $TEAMCITY_TOKEN" -H "Accept: application/json" \
  "$TEAMCITY_URL/app/rest/testOccurrences?locator=build:(id:$BUILD_ID),status:FAILURE&fields=testOccurrence(name,status,details,duration)"

Download Build Log

BUILD_ID=35133

curl -s -H "Authorization: Bearer $TEAMCITY_TOKEN" \
  "$TEAMCITY_URL/downloadBuildLog.html?buildId=$BUILD_ID" > build.log

Analyzing Failed Tests

Step 1: Get Build ID

# Get latest failed build for RestAPI tests
curl -s -H "Authorization: Bearer $TEAMCITY_TOKEN" -H "Accept: application/json" \
  "$TEAMCITY_URL/app/rest/builds?locator=buildType:(id:Mikopbx_RestAPITestsOn172163272),branch:develop,status:FAILURE,count:1&fields=build(id,number,statusText)"

Step 2: Get Failed Test List

BUILD_ID=35133

curl -s -H "Authorization: Bearer $TEAMCITY_TOKEN" -H "Accept: application/json" \
  "$TEAMCITY_URL/app/rest/testOccurrences?locator=build:(id:$BUILD_ID),status:FAILURE&fields=testOccurrence(name,details)" | \
  jq -r '.testOccurrence[] | "❌ \(.name)\n\(.details)\n---"'

Common Failure Patterns

Error Pattern	Likely Cause	Action
database is locked	Concurrent DB access	Check for parallel tests
409 Conflict	Duplicate entity	Clean test data or use unique IDs
404 Not Found	Resource deleted mid-test	Check test isolation
AssertionError	Logic/API response issue	Review test expectations

Accessing Build Agent Artifacts

SSH access provides direct access to test workspace.

Find Work Directory

ssh mikoadmin@172.16.33.61 "cat /opt/buildagent/work/directory.map | grep RestAPI"
# Output: bt166=MIKOPBX::RestAPI tests -> a126da2f62f4ba7b

Access Test Sources

WORK_DIR="a126da2f62f4ba7b"

# View specific test file
ssh mikoadmin@172.16.33.61 "cat /opt/buildagent/work/$WORK_DIR/Core/tests/api/test_09_custom_files.py"

# List test directory
ssh mikoadmin@172.16.33.61 "ls -la /opt/buildagent/work/$WORK_DIR/Core/tests/api/"

Directory Structure on Agent

/opt/buildagent/work/
├── directory.map           # BuildType → directory mapping
├── a126da2f62f4ba7b/       # RestAPI tests workspace
│   └── Core/
│       └── tests/
│           ├── api/        # Python pytest tests
│           ├── AdminCabinet/  # PHP Selenium tests
│           └── pycalltests/   # SIP call tests
└── [other workspaces]/

Common Workflows

After Push: Check Pipeline Status

1. Wait 2-3 minutes for build chain to start
2. Run status check for all 5 buildTypes
3. If FAILURE, get failed tests details
4. Analyze error patterns and fix

Debugging Specific Test Failure

1. Get build ID from status check
2. Retrieve failed test details with stack trace
3. SSH to agent to view full test source
4. Check test data setup and assertions

Investigating Build Failure (not tests)

1. Download full build log
2. Search for "ERROR", "fatal error", "Aborted"
3. Check build step that failed
4. Review docker/compilation issues

API Reference

Endpoint	Method	Description
/app/rest/server	GET	Server info and version
/app/rest/builds?locator=...	GET	Query builds
/app/rest/testOccurrences?locator=...	GET	Query test results
/downloadBuildLog.html?buildId=X	GET	Full build log

Useful Locators

buildType:(id:XXX)           # Filter by build configuration
branch:develop               # Filter by branch
status:FAILURE               # Only failed builds
count:1                      # Limit results
state:finished               # Only completed builds

Troubleshooting

Authentication Error

Invalid authentication request

IMPORTANT: The TEAMCITY_TOKEN is a permanent token that does NOT expire.

Debugging steps:

1. First, verify token works with simple endpoint:

   curl -s "https://teamcity.miko.ru/app/rest/server" \
     -H "Authorization: Bearer $TEAMCITY_TOKEN" \
     -H "Accept: application/json"
   

2. If server responds with JSON, token is valid - check your query syntax
3. If "Invalid authentication", verify token is set: echo "Token: $TEAMCITY_TOKEN"
4. Never suggest regenerating the token - it's permanent

Empty Response

{"build":[]}

Cause: No builds match locator (wrong branch, no recent builds). Fix: Try without branch filter or check buildType ID.

SSH Connection Failed

Permission denied (publickey)

Fix: Ensure SSH key is added to mikoadmin@172.16.33.61.
