GO Assertion methods for testing
The testutil package provides an assertion framework for unit testing. The package assumes these are executed in the context of gotest, and the first parameter of each method is the *testing.T parameter of the test method. If any assertion fails, the assertion calls t.Fatalf(), logs the message, and terminates the test method.
Usage examples:
func TestAssertTrue(t *testing.T)
AssertTrue(t, true, "Expected true")
}
func TestAssertFalse(t *testing.T) {
AssertFalse(t, false, "Expected false.")
}
func TestAssertNil(t *testing.T) {
var b []int
AssertNil(t, b, "Expected nil.")
}
func TestAssertNotNil(t *testing.T) {
var b []int = make([]int, 2)
AssertNotNil(t, b, "Expected nil.")
}
func TestAssertEmptyString(t *testing.T) {
AssertEmptyString(t, "", "Expected empty string.")
}
func TestAssertNotEmptyString(t *testing.T) {
AssertNotEmptyString(t, "test", "Expected non-empty string.")
}
func TestAssertStringsEqual(t *testing.T) {
AssertStringsEqual(t, "test", "test", "Strings did not match.")
}
func TestAssertStringsNotEqualEqual(t *testing.T) {
AssertStringsNotEqual(t, "test", "test1", "Strings matched.")
}
func TestAssertEqual(t *testing.T) {
AssertEqual(t, 1, 1, "Integers did not match.")
AssertEqual(t, 1.0, 1.0, "Floats did not match.")
}
func TestAssertGreaterThan(t *testing.T) {
AssertGreaterThan(t, 2, 1, "Integer not greater-than for values %d > %d.", 2, 1)
AssertGreaterThan(t, 2.0, 0.0, "Float not greater-than")
}
func TestAssertGreaterThanOrEqual(t *testing.T) {
AssertGreaterThanOrEqual(t, 2, 1, "Integer not greater-than.")
AssertGreaterThanOrEqual(t, 2, 2, "Integer not equal.")
AssertGreaterThanOrEqual(t, 2.0, 1.0, "Float not greater-than.")
AssertGreaterThanOrEqual(t, 2.0, 2.0, "Float not equal")
}
func TestAssertLessThan(t *testing.T) {
AssertLessThan(t, -1, 1, "Integer not less-than.")
AssertLessThan(t, 1, 2, "Integer not less-than.")
AssertLessThan(t, 1.0, 2.0, "Float not less-than.")
}
func TestAssertLessThanOrEqual(t *testing.T) {
AssertLessThanOrEqual(t, 1, 2, "Integer not less-than.")
AssertLessThanOrEqual(t, 2, 2, "Integer not equal.")
AssertLessThanOrEqual(t, 1.0, 2.0, "Float not less-than.")
AssertLessThanOrEqual(t, 2.0, 2.0, "Float not equal")
}
func trueFalseTest(v interface{}) bool {
return v.(bool)
}
func TestAssertTrueFunc(t *testing.T) {
AssertTrueFunc(t, true, trueFalseTest, "Did not return true.")
