| Enabled by default | No |
| Default severity | Info |
| Introduced in version | 3.4.0 |
Cause
This rule raises a diagnostic when there is a void [TestInitialize] method.
Rule description
It is usually better to rely on constructors for non-async initialization as you can then rely on readonly and get better compiler feedback when developing your tests. This is especially true when dealing with nullable enabled contexts.
How to fix violations
Replace [TestInitialize] returning void by constructors.
When to suppress warnings
You usually don't want to suppress warnings from this rule if you decided to opt-in for it.
