は、実際の違いは問題で予想と実際のコレクション/リストは重複にが含まれている専用の場合:
場合、それらはすべて失敗し、けれども:ユニーク値が実際のコレクションに欠けている
例を参照してください:
private List<String> withDuplicates;
private List<String> noDuplicates;
@Before
public void setUp() throws Exception {
withDuplicates = asList("Entryway", "Underhalls", "The Gauntlet", "Underhalls", "Entryway");
noDuplicates = asList("Entryway", "Underhalls", "The Gauntlet");
}
@Test
public void exactMatches_SUCCESS() throws Exception {
// successes because these 4 cases are exact matches (bored cases)
assertThat(withDuplicates).containsOnly("Entryway", "The Gauntlet", "Underhalls", "Entryway", "Underhalls"); // 1
assertThat(withDuplicates).containsExactlyInAnyOrder("Entryway", "The Gauntlet", "Underhalls", "Entryway", "Underhalls"); // 2
assertThat(noDuplicates).containsOnly("Entryway", "The Gauntlet", "Underhalls"); // 3
assertThat(noDuplicates).containsExactlyInAnyOrder("Entryway", "The Gauntlet", "Underhalls"); // 4
}
@Test
public void duplicatesAreIgnored_SUCCESS() throws Exception {
// successes because actual withDuplicates contains only 3 UNIQUE values
assertThat(withDuplicates).containsOnly("Entryway", "The Gauntlet", "Underhalls"); // 5
// successes because actual noDuplicates contains ANY of 5 expected values
assertThat(noDuplicates).containsOnly("Entryway", "The Gauntlet", "Underhalls", "Entryway", "Underhalls"); // 6
}
@Test
public void duplicatesCauseFailure_FAIL() throws Exception {
SoftAssertions.assertSoftly(softly -> {
// fails because ["Underhalls", "Entryway"] are UNEXPECTED in actual withDuplicates collection
softly.assertThat(withDuplicates).containsExactlyInAnyOrder("Entryway", "The Gauntlet", "Underhalls"); // 7
// fails because ["Entryway", "Underhalls"] are MISSING in actual noDuplicates collection
softly.assertThat(noDuplicates).containsExactlyInAnyOrder("Entryway", "The Gauntlet", "Underhalls", "Entryway", "Underhalls"); // 8
});
}
私は、 'containsOnly' javadocのそれを行うためのもう一つの理由はそれを明確にしようとしていました。 –
