Legacy release supporting MSRV < 1.39, including syn::export fix

New features

• Added support for using hamcrest2 assertions with test case
• Enabled support of async via tokio or similar
• Enabled attribute passthrough for test cases - it means that you can combine test-case with other testing frameworks,
  given at least one #[test_case] attribute appears before mentioned framework in testing function

Deprecation

• inconclusive inside test case name will not be supported starting 2.0.0

Overview

This crate provides #[test_case] procedural macro attribute that generates multiple parametrized tests using one body with different input parameters.
A test is generated for each data set passed in test_case attribute.
Under the hood, all test cases that share same body are grouped into mod, giving clear and readable test results.

New features

• Added support for three new keywords: panics, matches and inconclusive which can be applied after => token.

  matches gives possibility to test patterns, like:

  #[test_case("foo" => matches Some(("foo", _)))]

  panics gives should_panic(expected="...") for one test_case:

  #[test_case(true  => panics "Panic error message" ; "This should panic")]
  #[test_case(false => None                         ; "But this should return None")]

  inconclusive ignores one specific test case.- thanks to @luke-biel

  #[test_case("42")]
  #[test_case("XX" ; "inconclusive - parsing letters temporarily doesn't work, but it's ok")]
  #[test_case("na" => inconclusive ())]

Major improvements

• Added extra unit tests - thanks to @luke-biel
• Replace parented_test_case with parsing test_case directly from args - thanks to @luke-biel
• Added keeping trailing underscores in names - thanks to @rzumer

Minor improvements

• Moved lazy-static dependency to dev-dependencies
• Fixed README - thanks to @luke-biel and @drwilco

Upgraded dependencies

• Upgraded insta to 0.12.0

Bugfixes

• Fixed "inconclusive" feature with different cases.

    #[test_case(1 ; "this test is inconclusive and will always be")]
    #[test_case(2 ; "this test is also Inconclusive")]
    #[test_case(3 ; "this test is also INCONCLUSIVE even uppercase")]
    #[test_case(4 ; "this test is also iNCONCLUSIVE even inverted caps")]

Bugfixes

Breaking changes

• Crate has new maintainer: Wojciech Polak ✋ 🎉
• Crate has new name, as test-case-derive had no meaning for derive part.
• Delimiter for test case description is ; instead of ::.

Reason: :: is valid part of expression and rustc treats const variable as path

New features

• Proper error propagation 🎉
  When there is for example a typo in function body, rustc can now show location
  of it instead of test_case location.
• Internally for tests crate uses cargo insta for snapshot testing
• Attribute is now compatible with all other attributes like #[should_panic], however these attributes will be applied on every test case

Minor improvements:

• Refreshed readme
• Added CI for stable version of Rust. - thanks to @macisamuele
• Limited crate to Rust 1.29+ - thanks to @macisamuele

Upgraded dependencies:

• Upgraded syn, quote and proc-macro-2 to v1
• Upgraded lazy-static to 1.4.0
• Upgraded insta to 0.11.0
