A simple assertion library for go. Also see schema for easier JSON Schema testing.
go-test is fine. We do not need big testing frameworks for most projects. One thing its lacking though is simple assertions and ability to implement simple helpers as it does not allow us to skip test logs.
Trial gives us th.Error(t testingT, skip int, msgs ...interface{}) allowing to skip callers to implement helpers with nice logging.
For most uses, the trial/assert package is enough, giving us the most basic assertions needed with nice error messages.
Simple equals
import "github.com/jgroeneveld/trial/assert"
assert.Equal(t, 1, 2)
Output:
unit_test.go:42: Not equal:
Expected: 1
Actual: 2
Additional arguments to overwrite the message
assert.Equal(t, 1, 2, "numbers dont match for %q", "my param")
Output:
unit_test.go:42: numbers dont match for "my param":
Expected: 1
Actual: 2
Type problems are made clear
assert.Equal(t, 1, int64(1))
unit_test.go:42: Not equal:
Expected: 1
Actual: 1
Types: Expected:int, Actual:int64
See example/example_test.go for more.
Basic assertions
Equal(expected, actual, msgf...)
MustBeEqual(expected, actual, msgf...)
NotEqual(expected, actual, msgf...)
MustNotBeEqual(expected, actual, msgf...)
DeepEqual(expected, actual, msgf...)
MustBeDeepEqual(expected, actual, msgf...)
True(expression bool, msgf...)
MustBeTrue(expression bool, msgf...)
False(expression bool, msgf...)
MustBeFalse(expression bool, msgf...)
Nil(expression, msgf...)
MustBeNil(expression, msgf...)
NotNil(expression, msgf...)
MustNotBeNil(expression, msgf...)
JSON Schema assertions
JSONSchema(reader, matcher, msgf...)
MustMatchJSONSchema(reader, matcher, msgf...)
th can be used to write simple own assertions. This for example gives you a wrapper for schema.MatchJSON to have simple JSON schema assertions in your tests:
func AssertJSONSchema(t *testing.T, matcher schema.Matcher, r io.Reader) {
err := schema.MatchJSON(matcher, r)
if err != nil {
th.Error(t, 1, err.Error())
}
}
func MustMatchJSONSchema(t *testing.T, matcher schema.Matcher, r io.Reader) {
err := schema.MatchJSON(matcher, r)
if err != nil {
th.Error(t, 1, err.Error())
t.FailNow()
}
}
