Hi! What is the correct matcher for a parameter Supplier&lt;T&gt;?

You mean the Kotlin equivalent of a Java `Supplier`? It’s just a lambda type without arguments, returning T. Your function parameter would be:
```fun &lt;T&gt; myfunc(supplier: () -&gt; T) = ...```


I am using mockk and trying to use every{} to return a specific value, but I can’t figure out how to match the parameter of the method which is of type Supplier&lt;T&gt;

oh okay, there was some context missing in your message… so the type you want is probably
 `() -&gt; Any?` so you have to use an argument matcher on that, like `any&lt;() -&gt; Any?&gt;()`.

Thanks, looks like `any&lt;Supplier&lt;T&gt;&gt;()` does the job
