 ### Write Assertions
 
-The following Typescript example uses `Testing.synthScope` to test a part of the application. This creates a scope to test a subset of the application and returns a JSON string representing the synthesized HCL-JSON. Then it uses custom matchers to verify the code acts as intended.
+The following Typescript example uses `Testing.synth` to test a part of the application. Given the desired scope to test, a JSON string representing the synthesized HCL-JSON is returned. Then the custom assertions under `Testing` in the cdktf package can be used to verify the code acts as intended. `Testing.synth` can test the `Stack` that extends the `TerraformStack`.
