| Default severity | Info |
| Introduced in version | 3.4.0 |
Cause
This rule raises a diagnostic when there is a parameterless explicit constructor declared on a test class (class marked with [TestClass]).
Rule description
Use this rule to enforce using [TestInitialize] for both synchronous and asynchronous test initialization. Asynchronous (async/await) test intialization requires the use of [TestInitialize] methods, because the resulting Task needs to be awaited.
How to fix violations
Replace the constructor call with a [TestInitialize] method.
When to suppress warnings
You usually don't want to suppress warnings from this rule if you decided to opt-in for it.
