AssertThat Assertions

The assert_that is useful when you don’t know the type of the value you want to test.
You can use this assertion on all types you want, but for better readability of the test (GdScript) I prefer to use type store asserts. For C# you should prefer to use AssertThat, under C# the type of a variable is always known therefore it allows to find the right assert.

AssertThat Example

• GdScript
• C#

• Asserts are restricted by GdScript behavior and therefore do not fully support generics, i.e. you should prefer to use assert by type.
  

      func assert_that(<current>)
  

      assert_that("This is a test message").is_equal("This is a test message")
      assert_that(23).is_greater(20)
  

• The C# assert are smart and switch to the equivalent assert implementation by auto-typing and should also be used preferentially.
  

      // auto type assertion
      public static IAssertBase<Type> AssertThat(<current>);
  

      AssertThat("This is a test message").is_equal("This is a test message");
      AssertThat(23).IsGreater(20);
