Source:SoftAssertions.java
...19 * Suppose we have a test case and in it we'd like to make numerous assertions. In this case, we're hosting a dinner20 * party and we want to ensure not only that all our guests survive but also that nothing in the mansion has been unduly21 * disturbed:22 * <pre><code class='java'> @Test23 * public void host_dinner_party_where_nobody_dies() {24 * Mansion mansion = new Mansion();25 * mansion.hostPotentiallyMurderousDinnerParty();26 * assertThat(mansion.guests()).as("Living Guests").isEqualTo(7);27 * assertThat(mansion.kitchen()).as("Kitchen").isEqualTo("clean");28 * assertThat(mansion.library()).as("Library").isEqualTo("clean");29 * assertThat(mansion.revolverAmmo()).as("Revolver Ammo").isEqualTo(6);30 * assertThat(mansion.candlestick()).as("Candlestick").isEqualTo("pristine");31 * assertThat(mansion.colonel()).as("Colonel").isEqualTo("well kempt");32 * assertThat(mansion.professor()).as("Professor").isEqualTo("well kempt");33 * }</code></pre>34 *35 * <p>36 * After running the test, JUnit provides us with the following exception message:37 * <pre><code class='java'> org.junit.ComparisonFailure: [Living Guests] expected:<[7]> but was:<[6]></code></pre>38 *39 * <p>40 * Oh no! A guest has been murdered! But where, how, and by whom?41 * </p>42 *43 * <p>44 * Unfortunately frameworks like JUnit halt the test upon the first failed assertion. Therefore, to collect more45 * evidence, we'll have to rerun the test (perhaps after attaching a debugger or modifying the test to skip past the46 * first assertion). Given that hosting dinner parties takes a long time, this seems rather inefficient.47 * </p>48 *49 * <p>50 * Instead let's change the test so that at its completion we get the result of all assertions at once. We can do that51 * by using a SoftAssertions instance instead of the static methods on {@link Assertions} as follows:52 * <pre><code class='java'> @Test53 * public void host_dinner_party_where_nobody_dies() {54 * Mansion mansion = new Mansion();55 * mansion.hostPotentiallyMurderousDinnerParty();56 * SoftAssertions softly = new SoftAssertions();57 * softly.assertThat(mansion.guests()).as("Living Guests").isEqualTo(7);58 * softly.assertThat(mansion.kitchen()).as("Kitchen").isEqualTo("clean");59 * softly.assertThat(mansion.library()).as("Library").isEqualTo("clean");60 * softly.assertThat(mansion.revolverAmmo()).as("Revolver Ammo").isEqualTo(6);61 * softly.assertThat(mansion.candlestick()).as("Candlestick").isEqualTo("pristine");62 * softly.assertThat(mansion.colonel()).as("Colonel").isEqualTo("well kempt");63 * softly.assertThat(mansion.professor()).as("Professor").isEqualTo("well kempt");64 * softly.assertAll();65 * }</code></pre>66 *67 *68 * <p>69 * Now upon running the test our JUnit exception message is far more detailed:70 * <pre><code class='java'> org.assertj.core.api.SoftAssertionError: The following 4 assertions failed:71 * 1) [Living Guests] expected:<[7]> but was:<[6]>72 * 2) [Library] expected:<'[clean]'> but was:<'[messy]'>73 * 3) [Candlestick] expected:<'[pristine]'> but was:<'[bent]'>74 * 4) [Professor] expected:<'[well kempt]'> but was:<'[bloodied and disheveled]'></code></pre>75 *76 * <p>77 * Aha! It appears that perhaps the Professor used the candlestick to perform the nefarious deed in the library. We78 * should let the police take it from here.79 * </p>80 *81 * <p>You can also use the static method assertSoftly. the assertAll method will be called automatically after the lambda function completes.</p>82 * <pre><code class='java'> @Test83 * public void host_dinner_party_where_nobody_dies() {84 * Mansion mansion = new Mansion();85 * mansion.hostPotentiallyMurderousDinnerParty();86 * SoftAssertions.assertSoftly(softly -> {87 * softly.assertThat(mansion.guests()).as("Living Guests").isEqualTo(7);88 * softly.assertThat(mansion.kitchen()).as("Kitchen").isEqualTo("clean");89 * softly.assertThat(mansion.library()).as("Library").isEqualTo("clean");90 * softly.assertThat(mansion.revolverAmmo()).as("Revolver Ammo").isEqualTo(6);91 * softly.assertThat(mansion.candlestick()).as("Candlestick").isEqualTo("pristine");92 * softly.assertThat(mansion.colonel()).as("Colonel").isEqualTo("well kempt");93 * softly.assertThat(mansion.professor()).as("Professor").isEqualTo("well kempt");94 * });95 * }</code></pre>96 *97 * <p>98 * SoftAssertions works by providing you with proxies of the AssertJ assertion objects (those created by99 * {@link Assertions}#assertThat...) whose assertion failures are caught and stored. Only when you call100 * {@link SoftAssertions#assertAll()} will a {@link SoftAssertionError} be thrown containing the error messages of those101 * previously caught assertion failures.102 * </p>103 *104 * <p>105 * Note that because SoftAssertions is stateful you should use a new instance of SoftAssertions per test method. Also,106 * if you forget to call assertAll() at the end of your test, the test <strong>will pass</strong> even if any assertion107 * objects threw exceptions (because they're proxied, remember?). So don't forget. You might use108 * {@link JUnitSoftAssertions} or {@link AutoCloseableSoftAssertions} to get assertAll() to be called automatically.109 * </p>110 *111 * <p>112 * It is recommended to use {@link AbstractAssert#as(String, Object...)} so that the multiple failed assertions can be113 * easily distinguished from one another.114 * </p>115 *116 * @author Brian Laframboise117 *118 * @see <a href="http://beust.com/weblog/2012/07/29/reinventing-assertions/">Reinventing Assertions (inspired this feature)</a>119 */120public class SoftAssertions extends AbstractStandardSoftAssertions {121 /**122 * Verifies that no proxied assertion methods have failed.123 *124 * @throws SoftAssertionError if any proxied assertion objects threw125 */126 public void assertAll() {127 List<Throwable> errors = errorsCollected();128 if (!errors.isEmpty()) {129 throw new SoftAssertionError(extractProperty("message", String.class).from(errors));130 }131 }132 /**133 * Use this to avoid having to call assertAll manually.134 *135 * <pre><code class='java'> @Test136 * public void host_dinner_party_where_nobody_dies() {137 * Mansion mansion = new Mansion();138 * mansion.hostPotentiallyMurderousDinnerParty();139 * SoftAssertions.assertSoftly(softly -> {140 * softly.assertThat(mansion.guests()).as("Living Guests").isEqualTo(7);141 * softly.assertThat(mansion.kitchen()).as("Kitchen").isEqualTo("clean");142 * softly.assertThat(mansion.library()).as("Library").isEqualTo("clean");143 * softly.assertThat(mansion.revolverAmmo()).as("Revolver Ammo").isEqualTo(6);144 * softly.assertThat(mansion.candlestick()).as("Candlestick").isEqualTo("pristine");145 * softly.assertThat(mansion.colonel()).as("Colonel").isEqualTo("well kempt");146 * softly.assertThat(mansion.professor()).as("Professor").isEqualTo("well kempt");147 * });148 * }</code></pre>149 *150 * @param softly the SoftAssertions instance that you can call your own assertions on....
