Just run single test instead of the whole suite?
GoGo Problem Overview
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?
Go Solutions
Solution 1 - Go
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.
Solution 2 - Go
In case someone that is using Ginkgo BDD framework for Go will have the same problem, this could be achieved in that framework by marking test spec as focused (see docs), by prepending F before It, Context or Describe functions.
So, if you have spec like:
It("should be idempotent", func() {
You rewrite it as:
FIt("should be idempotent", func() {
And it will run exactly that one spec:
[Fail] testing Migrate setCurrentDbVersion [It] should be idempotent
...

Solution 3 - Go
Given a test:
func Test_myTest() {
//...
}
Run only that test with:
go test -run Test_myTest path/to/pkg/mypackage
Solution 4 - Go
Say your test suite is structured as following:
type MyTestSuite struct {
suite.Suite
}
func TestMyTestSuite(t *testing.T) {
suite.Run(t, new(MyTestSuite))
}
func (s *MyTestSuite) TestMethodA() {
}
To run a specific test of test suite in go, you need to use: -testify.m.
go test -v <package> -run ^TestMyTestSuite$ -testify.m TestMethodA
More simply, if the method name is unique to a package, you can always run this
go test -v <package> -testify.m TestMethodA
Solution 5 - Go
Simple and reliable:
go test -run TestMyFunction ./...

Solution 6 - Go
go test -v <package> -run <TestFunction>
