gotestsum runs tests using go test -json, prints formatted test output, and a summary of the test run. It is designed to work well for both local developments, and for automation like CI. When the --rerun-fails flag is set, gotestsum will re-run any failed tests. The tests will be re-run until each passes once, or the number of attempts exceeds the maximum attempts. Maximum attempts defaults to 2, and can be changed with --rerun-fails=n. gotestsum supports executing a compiled test binary (created with go test -c) by running it as a custom command. pkgname is the name of the package being tested, it will show up in the test output. ./binary.test is the path to the compiled test binary. The -test.v must be included so that go tool test2json receives all the output. When the --watch flag is set, gotestsum will watch directories using file system notifications.
