golang asserts and checks

Two set of assert and check functions for hard and soft unit test assertions in Go. The golang creators reject to create own testing framework, see Go FAQ about testing framework.

Inspired by:

• golang-assert
• python unittest library

Improvements:

• check functions
• frendlier error messages, including correct code line from tests
• In function for strings
• Error, NilError functions for functions that returns more than one parameter
• NilErr - short way to check no errors

The check functions are soft assertions. Failing tests will only be reported to the console via t.Errorf(). The assert functions are hard assertions. Failing tests will be reported to the console via t.Failf() and skip the current test execution.

Check equal

import "https://github.com/vizor-games/golang-unittest/check"

type Person struct {
    name string
    age  int
}

var paul = Person{
    name: "Paul",
    age:  32,
}

paul2 := paul

func TestEqual(t *testing.T) {
    check.Equal(t, paul, paul2, "Paul equals Paul")
}

Assert not equal

var peter = Person{
    name: "Peter",
    age:  21,
}

func TestNotEqual(t *testing.T) {
    assert.NotEqual(t, paul, peter, "Paul does not equal Peter")

Functions that returns additional error value

Use assert.J or check.J to convert args... to []interface{}:

func TestError(t *testing.T) {
    // "err is not nil for unexist file"
    assert.Error(t, assert.J(os.Open("unexist.file")))
}
