只是运行单个测试而不是整个套件？

Question

I have a test suite for a Go package that implements a dozen tests. Sometimes, one of the tests in the suite fails and I'd like to re-run that test individually to save time in debugging process. Is this possible or do I have to write a separate file for this every time?

Answer 1

Use the go test -run flag to run a specific test. The flag is documented in the testing flags section of the go tool documentation:

-run regexp
    Run only those tests and examples matching the regular
    expression.
