I use multiple programming languages and writing automated tests is one of the confusing parts. This is a cheat sheet to quickly check the difference of testing libraries.

Go

Go’s standard testing package doesn’t provide assert functions. A lot of projects use testify.

testify

• assert.Equal(t, expected, actual)
• require.Equal(t, expected, actual)

Perl

Test::More

• is(actual, expected)

Python

pytest

• assert expr

Rust

std

• assert_eq!(left, right)

It let developers decide which one is expected, according to the Rust Programming Language.

Java

Hamcrest

• assertThat(actual, matcher)

JUnit 5

• assertEquals(expected, actual)

TestNG

• assertEquals(actual, expected)
