Overview ¶
Package require implements the same assertions as the `assert` package but stops test execution when a test fails.
Example Usage ¶
The following is a complete example using require in a standard test function:
import ( "testing" "github.com/stretchr/testify/require" ) func TestSomething(t *testing.T) { var a string = "Hello" var b string = "Hello" require.Equal(t, a, b, "The two words should be the same.") }
Assertions ¶
The `require` package have same global functions as in the `assert` package, but instead of returning a boolean result they call `t.FailNow()`.
Every assertion function also takes an optional string message as the final argument, allowing custom error messages to be appended to the message the assertion method outputs.
