Frequently Asked Questions

What are the popular use cases of the Workik Golang Test Generator for developers?

FAQ open FAQ close

Popular use cases of Workik AI-powered Go Test Generator include but are not limited to:
1. Generating table-driven unit tests for critical Go functions
2. Auto-generating Go unit tests for new feature modules using the testing package or Testify
3. Writing mocks for interfaces using GoMock or Testify
4. Backfilling test coverage for legacy Go code
5. Creating test cases for API handlers, services, and edge-case scenarios
6. Bootstrapping test-first development in new Go microservices
7. Learning Go test practices by studying AI-generated examples
8. Bulk-generating *_test.go files for entire packages like handlers or services

What type of context can I add on Workik AI for Go test generation?

FAQ open FAQ close

While adding context is completely optional, adding it helps Workik AI in generating more accurate Golang test cases. You can add:
1. GitHub, GitLab, or Bitbucket repositories containing your Go source code
2. Framework preferences like Testify, GoMock, Ginkgo, or GoConvey
3. Package structures and target functions for focused test generation
4. Sample test files to align with your project’s testing style
5. API specs via Swagger or Postman to cover endpoint logic
6. Database schemas for generating tests involving queries or DB interaction

Is Workik AI useful for Golang TDD (Test-Driven Development)?

FAQ open FAQ close

Yes. Workik’s AI Go Test Generator is ideal for TDD workflows in Golang. You can define a function’s signature or logic outline, and generate expected test cases upfront. Then, develop the function to satisfy those tests—enabling clean test-first development with zero test debt.

Can I generate tests for multiple Go files at once using Workik AI?

FAQ open FAQ close

Yes — Workik AI lets you select a Go package or multiple .go files and automatically creates *_test.go files for each exported function. It supports struct methods, adds mocks, and follows Go’s standard testing conventions for fast and scalable test coverage. For example, a user package with 12 methods will output 12 *_test.go files—each with mocks, setup code, and table-driven tests ready to run.

Does Workik AI work with CI/CD pipelines?

FAQ open FAQ close

Yes. Workik AI integrates with GitHub Actions, GitLab CI, CircleCI, and more to automatically generate or update Go tests during your build process. You can trigger it on commits, pull requests, or specific file changes to keep coverage current without extra manual work.

Can Workik’s Free Go Test Generator help backfill tests for legacy Golang services?

FAQ open FAQ close

Yes, Workik AI scans legacy Go code, identifies untested logic, and generates full test cases with mocks and edge-case coverage. For example, a Go API from 2017 with zero test cases can hit 90%+ test coverage with thorough handler, service, and DB layer tests in no time using Workik AI.

Do I need to regenerate all tests when my codebase changes?

FAQ open FAQ close

No. You can select only the updated or relevant Go files, and Workik AI will generate or update test cases accordingly. This keeps your workflow efficient without reprocessing the entire codebase.

Does Workik support Go test generation for cloud-native apps?

FAQ open FAQ close

Yes. Workik AI is ideal for testing Go-based cloud-native applications. Whether you're working with REST APIs, gRPC services, or cloud functions, Workik can generate handler-level unit tests that mock cloud dependencies like S3 clients, pub/sub systems, or database connections. It can also simulate edge cases—such as retries, timeouts, rate-limiting, and error responses—ensuring resilient, production-grade test coverage.

Can I collaborate with teammates inside Workik workspaces?

FAQ open FAQ close

Yes. You can invite team members to shared workspaces to co-generate, edit, and review Go test files. It's perfect for collaborative testing, pair programming, or onboarding new devs into your testing workflows.
