Introduction

The java exercisedownloader example is extracted from the most popular open source projects, you can refer to the following example for usage.

Programming language: Java

Namespace/package name: hy.tmc.core.communication

Example#1
File: DownloadExercisesTest.javaProject: jamox/tmc-core

  @Test
  public void overwritesToCacheFileIfCacheFileHasBadContents()
      throws IOException, TmcCoreException {
    new FileWriter(cache).write(" asdfjljlkasdf ");

    ExerciseDownloader downloader = Mockito.mock(ExerciseDownloader.class);
    Mockito.when(downloader.createCourseFolder(anyString(), anyString())).thenReturn("");
    Mockito.when(downloader.handleSingleExercise(any(Exercise.class), anyString()))
        .thenReturn(true);

    Course course = new Course();
    course.setName("test-course");
    course.setExercises(
        new ExerciseBuilder()
            .withExercise("kissa", 2, "eujwuc")
            .withExercise("asdf", 793, "alnwnec")
            .withExercise("ankka", 88, "abcdefg")
            .build());

    parser = Mockito.mock(TmcJsonParser.class);

    Mockito.when(parser.getCourse(anyInt())).thenReturn(Optional.of(course));

    DownloadExercises dl = new DownloadExercises(downloader, "", "8", cache, settings, parser);
