v0.11.0

API Changes

• The Minimum Rust Supported Version was updated from 1.59 to 1.66

• The property! and matches_pattern! matchers use * instead of ref to handle properties returned by reference.
  For instance, to match the following structure:

  struct Strukt { a_field: i32 }
  impl Strukt {
    fn get_a_field(&self) -> &i32 {&self.a_field}
  }
  

  OLD:

  verify_that(Strukt{a_field: 123}, property!(ref Strukt.get_a_field(), eq(123))
  

  NEW:

  verify_that(Strukt{a_field: 123}, property!(*Strukt.get_a_field(), eq(123))
  

• Macro matchers are not exported on the top level anymore but exported in the googletest::matchers module as well as the googletest::prelude module.
  OLD:

  use googletest::elements_are;
  verify_that(vec![1,2,3], elements_are![1,2,3])
  

  NEW:

  use googletest::matchers::elements_are;
  verify_that(vec![1,2,3], elements_are![1,2,3])
  

• Matcher::explain_match and Matcher::describe now returns a Description instead of a String. Handling of wrapping matcher motivated this change and will make them simpler to write. For simple matchers, this change should be straightforward.
  OLD:

  impl Matcher for MyMatcher {
    ...
    fn explain_match(&self, actual: &Self::Actual) -> String {
      "explanation".to_string()
    }
    fn describe(&self) -> String {
      "description".to_string()
    }
  }
  

  NEW:

  impl Matcher for MyMatcher {
    ...
    fn explain_match(&self, actual: &Self::Actual) -> Description {
      "explanation".into()
    }
    fn describe(&self) -> Description {
      "description".into()
    }
  }
  

Other new features and improvements

• is_utf8_string(...) is a new matcher which matches a byte array with proper ut8 encoding.
• assert_that! and expect_that! accepts an error message as third argument, like assert_eq!(...).
• Trailing commas support in assert_that!, expect_that!, elements_are!, and unordered_elements_are!
• Diff summary will highlight the mismatching line with colors.
• #[should_panic] can be used with the #[googletest::test] macro.

Other minor changes

• When using eq(...) with different types (e.g. String and &str), the PartialEq relationship has been switched. See #334 for more details.
• Documentation fix in #299 and #332
• Add an extra whitespace between subsequent non-fatal failure messages.
