Overview

This crate provides the #[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 the test_case attribute.
Under the hood, all test cases that share the same body are grouped into a mod, giving clear and readable test results.

Changes

• Split out test-case-core crate, allowing easier reuse in external crates. By @evforde

IMPORTANT

Starting with the 3.0 release, we are changing test-case MSRV policy. We no longer can maintain our goal of only bumping MSRV with major SemVer releases partly due to how fast rust landscape changes and partly to how the rest of the rust ecosystem prefers instead not to keep MSRV breakage treated as SemVer breakage, making stricter policies hard to maintain with limited resources we have. The current goal is to support up to 3 of the latest stable releases.
We hope that with this change, we'll be able to speed up test-case's maintenance processes and add more features in the coming months.

[IMPORTANT] Starting with 3.0 release we are changing test-case MSRV policy to support only 3 latest stable releases.

Improvements

• Split out functional parts of test-case-macros crate into test-case-core for easy reuse by external libraries
