go get github.com/MarvinJWendt/testzaDescription
Testza is a full-featured testing framework for Go.
It integrates with the default test runner, so you can use it with the standard go test tool.
Testza contains easy to use methods, like assertions, output capturing, mocking, and much more.
The main goal of testza is to provide an easy and fun experience writing tests and providing a nice, user-friendly output. Even developers who never used testza, will get into it quickly.
Getting Started
See the examples below for a quick introduction!
// --- Some Examples ---
// - Some assertions -
testza.AssertTrue(t, true) // -> Pass
testza.AssertNoError(t, err) // -> Pass
testza.AssertEqual(t, object, object) // -> Pass
// ...
// - Testing console output -
// Test the output of your CLI tool easily!
terminalOutput, _ := testza.CaptureStdout(func(w io.Writer) error {fmt.Println("Hello"); return nil})
testza.AssertEqual(t, terminalOutput, "Hello\n") // -> Pass
// - Mocking -
// Testing a function that accepts email addresses as a parameter:
// Testset of many different email addresses
emailAddresses := testza.MockStringEmailAddresses()
// Run a test for every string in the test set
testza.MockStringRunTests(t, emailAddresses, func(t *testing.T, index int, str string) {
user, domain, err := internal.ParseEmailAddress(str) // Use your function
testza.AssertNoError(t, err) // Assert that your function does not return an error
testza.AssertNotZero(t, user) // Assert that the user is returned
testza.AssertNotZero(t, domain) // Assert that the domain is returned
})
// And that's just a few examples of what you can do with Testza!Documentation
Assert
AssertCompletesIn
func AssertCompletesIn(t testRunner, duration time.Duration, f func(), msg ...interface{})AssertCompletesIn asserts that a function completes in a given time. Use this function to test that functions do not take too long to complete.
NOTE: Every system takes a different amount of time to complete a function. Do not set the duration too low, if you want consistent results.

// some code that should take less than 2 seconds...
}) // => PASS
AssertContains

}
Snapshot
SnapshotCreate
func SnapshotCreate(name string, snapshotObject interface{}) errorSnapshotCreate creates a snapshot of an object, which can be validated in future test runs. Using this function directly will override previous snapshots with the same name. You most likely want to use SnapshotCreateOrValidate.
NOTICE: \r\n will be replaced with \n to make the files consistent between operating systems.
Example:
testza.SnapshotCreate(t.Name(), objectToBeSnapshotted)
SnapshotCreateOrValidate
func SnapshotCreateOrValidate(t testRunner, name string, object interface{}, msg ...interface{}) errorSnapshotCreateOrValidate creates a snapshot of an object which can be used in future test runs. It is good practice to name your snapshots the same as the test they are created in. You can do that automatically by using t.Name() as the second parameter, if you are using the inbuilt test system of Go. If a snapshot already exists, the function will not create a new one, but validate the exisiting one. To re-create a snapshot, you can delete the according file in /testdata/snapshots/.
NOTICE: \r\n will be replaced with \n to make the files consistent between operating systems.
Example:
testza.SnapshotCreateOrValidate(t, t.Name(), object)
testza.SnapshotCreateOrValidate(t, t.Name(), object, "Optional Message")
SnapshotValidate
func SnapshotValidate(t testRunner, name string, actual interface{}, msg ...interface{}) errorSnapshotValidate validates an already exisiting snapshot of an object. You most likely want to use SnapshotCreateOrValidate.
NOTICE: \r\n will be replaced with \n to make the files consistent between operating systems.
Example:
testza.SnapshotValidate(t, t.Name(), objectToBeValidated)
testza.SnapshotValidate(t, t.Name(), objectToBeValidated, "Optional message")
