Method Detail

verify

public static void verify(java.lang.Object output)

Compares the actual output of your program (the function’s argument) and the content of the approved file matching with the test method.

It’ll use a temporary received file to store the output of your program. This file will be erased in case the results are matching. Otherwise, it will be kept for you to review it.

In case of differences found in the output, the Reporter linked to this Approvals instance will be called (Reporter.mismatch(Path, Path)).

Parameters:

output - Any object with a Object.toString() representation containing the output of your program. It will be compared to the associated approved file.

Throws:

java.lang.AssertionError - if the Reporter implementation relies on standard assertions provided by a framework like JUnit

java.lang.RuntimeException - if the Reporter relies on executing an external command which failed

verifyAllFiles

public static void verifyAllFiles(java.nio.file.Path actualFolder)

Compares the actual output of your program (files in the folder actualFolder) and the content of the approved “Master” folder matching with the test method.

It’ll use a temporary received folder to copy the actual files from your program. This folder and its files will be erased in case the results are matching. Otherwise, they will be kept for you to review it.

In case of differences found in the output, the Reporter linked to this Approvals instance will be called (Reporter.mismatch(Path, Path)) for each mismatched file.

Parameters:

actualFolder - the folder containing the output of your program. It will be compared to the associated approved folder

Throws:

java.lang.AssertionError - if the Reporter implementation relies on standard assertions provided by a framework like JUnit

java.lang.RuntimeException - if the Reporter relies on executing an external command which failed
