+ The simplest method list is a single method name specified using just the method name (no class name), e.g. `Main`.
+ A list of simple method names can be used, e.g., `Main Test1 Test2`.
* The string matched against depends on characters in the pattern:
+ If the pattern contains a '!' character, the string matched against is prefixed by the assembly name and an exclamation mark.
- Example: `testassembly!*` - specifies all methods from the assembly named `testassembly`.
+ If the pattern contains a ':' character, the string matched against is prefixed by the class name and a colon.
- Example: `TestClass:Main` - specifies a single method named `Main` in the class named `TestClass`.
+ If the pattern contains a '(' character, the string matched against is suffixed by the signature.
