parameterized
Procedural macro which allows you to define a test to be run with multiple (optionally different) arguments.
Test cases are defined using the 'parameterized' attribute instead of the 'test' attribute.
This crate was inspired by JUnit @ParameterizedTest
.
Examples:
Example: Add5
Example: Fruits
Additional examples can be found here (parameterized-examples repo) and in the tests folder.
Imports
If you prefer not to import this library with use parameterized::parameterized;
in every test case, you can put
the following snippet at the top of your crate root:
extern crate parameterized;
IDE 'run test' intent
IntelliJ IDEA recognizes test cases and provides context menu's which allow you to run tests within a certain scope
(such as a module or a single test case). For example, in IntelliJ you can usually run individual test cases by clicking
the ▶ icon in the gutter. Unfortunately, attribute macros are currently not expanded by intellij-rust
.
This means that the IDE will not recognize test cases generated as a result of attribute macros (such as the
parameterized
macro published by this crate). As a partial work around, you can create an empty test case which
will mark the module as containing test cases and in the gutter you will find a ▶ icon next to the module. This allows
you to run test cases per module. This crate provides a macro called ide!()
which creates an empty test case for
the above purpose.
Note: intellij-rust
does expand declarative macro's (at least with the new macro engine which can be
selected in the 'settings' menu), such as this ide!
macro.
