title: MsTest - executing method before each test in an assembly
body: <p>Is it possible to run specific method before each test in an assembly?</p>
  
  <p>I know about <code>TestInitialize</code> attribute but this attribute has "class scope". If it's defined in a Test class it will be executed before each test from this class. </p>
  
  <p>I want to define a method that will be executed before each test defined in a whole assembly.</p>
