Parameterized Tests.
Singleton (i.e Input, OS, Time) doubling.
Engine error detection and "handling" via Error Tracking.

Getting Started

extends GutTest

func before_all():
    gut.p("ran run setup")

func before_each():
    gut.p("ran setup")

func after_each():
    gut.p("ran teardown")

func after_all():
    gut.p("ran run teardown")

func test_passes():
    # this test will pass because 1 does, in fact, equal 1
    assert_eq(1, 1)

func test_fails():

IMO, This addon is a must-have for any non-trivial project. Writing tests can be a bit annoying at first, but you'll thank yourself as your project grows and becomes more difficult to manage.

Gran addon. Programar tests unitarios es un trabajo extra importante pero el beneficio de disponer de pruebas automatizadas para tener claro siempre qué es lo que se a roto es muy grande. No todo requiere pruebas unitarias pero para algunas cosas lo veo fundamental. En estos momentos ya estaba haciendo mis escenas de pruebas. Ahora las podré automatizar con este addon y dejarlas ahí que se ejecuten solas cada vez que tenga dudas sobre si habré roto o no algo. Gracias por el addon.

Es un Addon bastante util, facil de usar y ahorra mucho trabajo. El unico problema que he tenido con el es que cada vez que lo instalo en un proyecto (lo he hecho dos veces), da un monton de errores al cargar y tengo que reiniciar Godot hasta que por fin agarra. No se si es un error del plugin o de mi parte, pero cuando agarra es tremenda herramienta, lo recomiendo.

Don't use this for your prototype, but if you are expecting +6months into development, consider using this addon to avoid repeating manually tests. Remember, your future self at 1am will not see those bugs as the code will
