Debugging ts-jest

You can activate the debug logger by setting the environment variable TS_JEST_LOG before running tests. The output of the logger will be in ts-jest.log in current working directory.

The debug logger contains some useful information about how internal ts-jest works, including which files are processed, which Jest config or TypeScript config is used etc.


export TS_JEST_LOG=ts-jest.log


set TS_JEST_LOG=ts-jest.log
