From 3e64f7ae2ab82f5b7984c65079896c652225918a Mon Sep 17 00:00:00 2001 From: Hein Date: Fri, 2 Jan 2026 23:08:17 +0200 Subject: [PATCH] feat(testing): add full integration test suite This commit introduces a comprehensive integration test suite for the pgsql-broker. The test suite includes: - A Docker/Podman environment for running a PostgreSQL database, managed via a . - Integration tests that cover the broker's lifecycle, including job creation, execution, and instance management. - A GitHub Actions workflow to automate the execution of all tests on push and pull requests. - A dedicated test configuration file () and helper test files. refactor(worker): fix job processing transaction - The worker's job processing now uses a single transaction to fetch and run a job, resolving a race condition where jobs were not in the 'running' state when being executed. - The broker's database instance registration is now more robust, handling cases where another instance is already active. The Makefile has been significantly updated to orchestrate the entire test flow, including setting up the database, starting/stopping the broker, and running unit and integration tests separately. --- .github/workflows/integration.yml | 33 +++++ .gitignore | 1 + .golangci.json | 114 ++++++++++++++++++ AI_USE.md | 35 ++++++ Makefile | 57 +++++++-- broker.test.yaml | 25 ++++ go.mod | 4 + pkg/broker/database_instance.go | 57 ++++++++- pkg/broker/install/sql/tables/00_install.sql | 6 +- ...er_schedule.sql => 02_broker_schedule.sql} | 0 ...{02_broker_jobs.sql => 03_broker_jobs.sql} | 0 pkg/broker/worker/worker.go | 45 ++++--- tests/docker-compose.yml | 10 ++ tests/integration/connection_test.go | 31 +++++ tests/integration/main_test.go | 13 ++ tests/integration/workflow_test.go | 9 ++ 16 files changed, 406 insertions(+), 34 deletions(-) create mode 100644 .github/workflows/integration.yml create mode 100644 .golangci.json create mode 100644 AI_USE.md create mode 100644 broker.test.yaml rename pkg/broker/install/sql/tables/{03_broker_schedule.sql => 02_broker_schedule.sql} (100%) rename pkg/broker/install/sql/tables/{02_broker_jobs.sql => 03_broker_jobs.sql} (100%) create mode 100644 tests/docker-compose.yml create mode 100644 tests/integration/connection_test.go create mode 100644 tests/integration/main_test.go create mode 100644 tests/integration/workflow_test.go diff --git a/.github/workflows/integration.yml b/.github/workflows/integration.yml new file mode 100644 index 0000000..390411a --- /dev/null +++ b/.github/workflows/integration.yml @@ -0,0 +1,33 @@ +name: Integration Tests + +on: + push: + branches: + - main + pull_request: + branches: + - main + +jobs: + integration-test: + runs-on: ubuntu-latest + + steps: + - name: Checkout code + uses: actions/checkout@v3 + + - name: Set up Go + uses: actions/setup-go@v3 + with: + go-version: '1.21' + + - name: Set up Python + uses: actions/setup-python@v4 + with: + python-version: '3.x' + + - name: Install podman-compose + run: pip install podman-compose + + - name: Run all tests + run: make test-all diff --git a/.gitignore b/.gitignore index d19aac0..d98dac4 100644 --- a/.gitignore +++ b/.gitignore @@ -50,3 +50,4 @@ Thumbs.db # Coverage coverage.html +broker.pid diff --git a/.golangci.json b/.golangci.json new file mode 100644 index 0000000..436536b --- /dev/null +++ b/.golangci.json @@ -0,0 +1,114 @@ +{ + "formatters": { + "enable": [ + "gofmt", + "goimports" + ], + "exclusions": { + "generated": "lax", + "paths": [ + "third_party$", + "builtin$", + "examples$" + ] + }, + "settings": { + "gofmt": { + "simplify": true + }, + "goimports": { + "local-prefixes": [ + "git.warky.dev/wdevs/relspecgo" + ] + } + } + }, + "issues": { + "max-issues-per-linter": 0, + "max-same-issues": 0 + }, + "linters": { + "enable": [ + "gocritic", + "misspell", + "revive" + ], + "exclusions": { + "generated": "lax", + "paths": [ + "third_party$", + "builtin$", + "examples$", + "mocks?", + "tests?" + ], + "rules": [ + { + "linters": [ + "dupl", + "errcheck", + "gocritic", + "gosec" + ], + "path": "_test\\.go" + }, + { + "linters": [ + "errcheck" + ], + "text": "Error return value of .((os\\.)?std(out|err)\\..*|.*Close|.*Flush|os\\.Remove(All)?|.*print(f|ln)?|os\\.(Un)?Setenv). is not checked" + }, + { + "path": "_test\\.go", + "text": "cognitive complexity|cyclomatic complexity" + } + ] + }, + "settings": { + "errcheck": { + "check-blank": false, + "check-type-assertions": false + }, + "gocritic": { + "enabled-checks": [ + "boolExprSimplify", + "builtinShadow", + "emptyFallthrough", + "equalFold", + "indexAlloc", + "initClause", + "methodExprCall", + "nilValReturn", + "rangeExprCopy", + "rangeValCopy", + "stringXbytes", + "typeAssertChain", + "unlabelStmt", + "unnamedResult", + "unnecessaryBlock", + "weakCond", + "yodaStyleExpr" + ], + "disabled-checks": [ + "ifElseChain" + ] + }, + "revive": { + "rules": [ + { + "disabled": true, + "name": "exported" + }, + { + "disabled": true, + "name": "package-comments" + } + ] + } + } + }, + "run": { + "tests": true + }, + "version": "2" +} \ No newline at end of file diff --git a/AI_USE.md b/AI_USE.md new file mode 100644 index 0000000..397857c --- /dev/null +++ b/AI_USE.md @@ -0,0 +1,35 @@ +# AI Usage Declaration + +This Go project utilizes AI tools for the following purposes: + +- Generating and improving documentation +- Writing and enhancing tests +- Refactoring and optimizing existing code + +AI is **not** used for core design or architecture decisions. +All design decisions are deferred to human discussion. +AI is employed only for enhancements to human-written code. + +We are aware of significant AI hallucinations; all AI-generated content is to be reviewed and verified by humans. + + + .-""""""-. + .'
