 ## Overview
 
 This tool lets you write tests for your type definitions (i.e. your `.d.ts` files) by creating files with the `.test-d.ts` extension.
 
 These `.test-d.ts` files will not be executed, and not even compiled in the standard way. Instead, these files will be parsed for special constructs such as `expectError<Foo>(bar)` and then statically analyzed against your type definitions.

 ## Usage
 
 Let's assume we wrote a `index.d.ts` type definition for our concat module.

 ## Programmatic API
 
 You can use the programmatic API to retrieve the diagnostics and do something with them. This can be useful to run the tests with AVA, Jest or any other testing framework.
 
 ```ts
 import tsd from 'tsd';
 
-(async () => {
-	const diagnostics = await tsd();
+const diagnostics = await tsd();
 
-	console.log(diagnostics.length);
-	//=> 2
-})();
+console.log(diagnostics.length);
