Writing test boilerplate is tedious. TestCraft does the boring part so you can focus on assertions.
Generates correct import statements for every test file. Handles relative paths, package names, and framework-specific imports automatically.
Creates setup/teardown methods for class-based tests. Proper initialization, mock objects, and cleanup — all scaffolded correctly.
Generates parameterized test stubs for functions with multiple code paths. Boundary values, null inputs, and error cases included.
Never overwrites existing test files. Skips test files, __init__.py, config files, and private functions. Your existing tests are always safe.
TestCraft fits wherever test coverage matters.
Got a project with zero tests? TestCraft generates the entire test structure in seconds. Fill in the assertions and you're covered.
Moving from unittest to pytest? Mocha to Vitest? Generate fresh test scaffolding in the new framework without rewriting boilerplate.
Write your feature code first, then run TestCraft to generate test stubs. Faster than writing test boilerplate by hand every time.
Before submitting a PR, run TestCraft to see what's untested. Coverage report shows exactly which functions need test cases.
One command generates test stubs for your entire codebase. Stop writing boilerplate, start writing assertions.
