     Therefore, it is common practice here to write an OCI Runtime Spec that executes `runtimetest`.
 
 ```rust,no_run,noplayground
-{{#include ../../../../tests/integration_test/src/tests/example/hello_world.rs:get_example_spec}}
+{{#include ../../../../tests/contest/contest/src/tests/example/hello_world.rs:get_example_spec}}
 ```
 
 2. Prepare a function that returns a `TestResult`, which represents the result of the test.
 
 ```rust,no_run,noplayground
-{{#include ../../../../tests/integration_test/src/tests/example/hello_world.rs:example_test}}
+{{#include ../../../../tests/contest/contest/src/tests/example/hello_world.rs:example_test}}
 ```
 
 3. Create a `TestGroup` and register a test case you created
 
 ```rust,no_run,noplayground
-{{#include ../../../../tests/integration_test/src/tests/example/hello_world.rs:get_example_test}}
+{{#include ../../../../tests/contest/contest/src/tests/example/hello_world.rs:get_example_test}}
 ```
 
 4. Register the `TestGroup` you created to a `TestManager`
 
 ```rust,no_run,noplayground
-{{#include ../../../../tests/integration_test/src/main.rs:register_example_test}}
+{{#include ../../../../tests/contest/contest/src/main.rs:register_example_test}}
 ```
 
 5. Write the validation you want to run within a test container
 ```rust,no_run,noplayground
-{{#include ../../../../tests/runtimetest/src/main.rs:example_runtimetest_main}}
+{{#include ../../../../tests/contest/runtimetest/src/main.rs:example_runtimetest_main}}
 ```
 ```rust,no_run,noplayground
-{{#include ../../../../tests/runtimetest/src/tests.rs:example_hello_world}}
