@@ -14,40 +20,51 @@ This page covers advanced features of `ParallelTestRunner` for customizing test
 By default, [`runtests`](@ref) automatically discovers all `.jl` files in your `test/` directory (excluding `runtests.jl` itself) using the `find_tests` function.
 You can customize which tests to run by providing a custom `testsuite` dictionary:
 
-```julia
+```@example mypackage
+using ParallelTestRunner
+using MyPackage
+
 # Manually define your test suite
 testsuite = Dict(
     "basic" => quote
         include("basic.jl")
     end,
     "advanced" => quote
         include("advanced.jl")
+        @test 40 + 2 ≈ 42
     end
 )
 
-runtests(MyModule, ARGS; testsuite)
+cd(test_dir) do # hide
+runtests(MyPackage, ARGS; testsuite)
+end # hide
 ```
 
 ## Filtering Test Files
 
 You can also use [`find_tests`](@ref) to automatically discover test files and then filter or modify them.
 This requires manually parsing arguments so that filtering is only applied when the user did not request specific tests to run:
 
-```julia
+```@example mypackage
+using ParallelTestRunner
+using MyPackage
+
 # Start with autodiscovered tests
+cd(test_dir) do # hide
 testsuite = find_tests(pwd())
 
 # Parse arguments
 args = parse_args(ARGS)
 
 if filter_tests!(testsuite, args)
-    # Remove tests that shouldn't run on Windows
-    if Sys.iswindows()
-        delete!(testsuite, "ext/specialfunctions")
+    # Remove tests that shouldn't run on non-Windows systems
+    if !Sys.iswindows()
+        delete!(testsuite, "advanced")
     end
 end
 
-runtests(MyModule, args; testsuite)
+runtests(MyPackage, args; testsuite)
+end # hide
 ```
 
 The [`filter_tests!`](@ref) function returns `true` if no positional arguments were provided (allowing additional filtering) and `false` if the user specified specific tests (preventing further filtering).
