Skip to main content

Simple and convenient way to fetch file content in Java8

If you've used Wiremock to mock an external service, you know its possible to set the response returned as a String.

When setting the mocked service response, I usually save the response from the real service in the src/test/resource folder and extract the file content using the method below.

private static String getResponse(String path) throws IOException {
  return new String(Files.readAllBytes(Paths.get(path)));
}

Here is how to call the method above fetching the content of a file located in the test resource folder.

getResponse("src/test/resources/responses/filename.json")
