Potentially unused parameter in go when using testify's suite package-CodePudding

I want to execute subtests using the testify/suite package.

I am declaring my Unit suite as follows


type UnitSuite struct {
    suite.Suite
}

func TestUnitSuite(t *testing.T) {
    suite.Run(t, &UnitSuite{})
}

and here is my subtest

func (us *UnitSuite) ΤestSomething() {
    for i := range testVars {
        i := i
        us.T().Run(testVars[i].name, func(t *testing.T) {
        ...

Ι am getting the following linting warning for func(t *testing.T)

potentially unused parameter: 't'unusedparams

When trying to substitute with the testing suite's function T() that is supposes to retrieve the testing context

us.T().Run(testVars[i].name, func(us.T()) {

I get this error in func(us.T()) <-- errors out

missing ',' in parameter listsyntax

What is the way to go about this that does not produce neither errors nor linting warnings?

CodePudding user response：

If you want to declare an unused parameter (usually to satisfy an interface or other requirements), you can name it a single underscore. For example:

Run(name, func(_ *testing.T) {})

Note that you cannot put a value in function declaration, so func(us.T()) { is always wrong.
