How to use extractProperty method of org.assertj.core.api.BDDAssertions class

Best Assertj code snippet using org.assertj.core.api.BDDAssertions.extractProperty

Source:BDDSoftAssertions.java

...11 * Copyright 2012-2015 the original author or authors.12 */13package org.assertj.core.api;14import java.util.List;15import static org.assertj.core.groups.Properties.extractProperty;16/**17 * <p>18 * Suppose we have a test case and in it we'd like to make numerous BDD assertions. In this case, we're hosting a dinner19 * party and we want to ensure not only that all our guests survive but also that nothing in the mansion has been unduly20 * disturbed:21 * <pre><code class='java'> &#064;Test22 * public void host_dinner_party_where_nobody_dies() {23 *   Mansion mansion = new Mansion();24 *   mansion.hostPotentiallyMurderousDinnerParty();25 *   then(mansion.guests()).as(&quot;Living Guests&quot;).isEqualTo(7);26 *   then(mansion.kitchen()).as(&quot;Kitchen&quot;).isEqualTo(&quot;clean&quot;);27 *   then(mansion.library()).as(&quot;Library&quot;).isEqualTo(&quot;clean&quot;);28 *   then(mansion.revolverAmmo()).as(&quot;Revolver Ammo&quot;).isEqualTo(6);29 *   then(mansion.candlestick()).as(&quot;Candlestick&quot;).isEqualTo(&quot;pristine&quot;);30 *   then(mansion.colonel()).as(&quot;Colonel&quot;).isEqualTo(&quot;well kempt&quot;);31 *   then(mansion.professor()).as(&quot;Professor&quot;).isEqualTo(&quot;well kempt&quot;);32 * }</code></pre>33 * </p>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:&lt;[7]&gt; but was:&lt;[6]&gt;</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 BDDSoftAssertions instance instead of the static methods on {@link BDDAssertions} as follows:52 * <pre><code class='java'> &#064;Test53 * public void host_dinner_party_where_nobody_dies() {54 *   Mansion mansion = new Mansion();55 *   mansion.hostPotentiallyMurderousDinnerParty();56 *   BDDSoftAssertions softly = new BDDSoftAssertions();57 *   softly.then(mansion.guests()).as(&quot;Living Guests&quot;).isEqualTo(7);58 *   softly.then(mansion.kitchen()).as(&quot;Kitchen&quot;).isEqualTo(&quot;clean&quot;);59 *   softly.then(mansion.library()).as(&quot;Library&quot;).isEqualTo(&quot;clean&quot;);60 *   softly.then(mansion.revolverAmmo()).as(&quot;Revolver Ammo&quot;).isEqualTo(6);61 *   softly.then(mansion.candlestick()).as(&quot;Candlestick&quot;).isEqualTo(&quot;pristine&quot;);62 *   softly.then(mansion.colonel()).as(&quot;Colonel&quot;).isEqualTo(&quot;well kempt&quot;);63 *   softly.then(mansion.professor()).as(&quot;Professor&quot;).isEqualTo(&quot;well kempt&quot;);64 *   softly.assertAll();65 * } </code></pre>66 * 67 * <p>68 * Now upon running the test our JUnit exception message is far more detailed:69 * <pre><code class='java'> org.assertj.core.api.SoftAssertionError: The following 4 assertions failed:70 * 1) [Living Guests] expected:&lt;[7]&gt; but was:&lt;[6]&gt;71 * 2) [Library] expected:&lt;'[clean]'&gt; but was:&lt;'[messy]'&gt;72 * 3) [Candlestick] expected:&lt;'[pristine]'&gt; but was:&lt;'[bent]'&gt;73 * 4) [Professor] expected:&lt;'[well kempt]'&gt; but was:&lt;'[bloodied and disheveled]'&gt;</code></pre>74 * 75 * <p>76 * Aha! It appears that perhaps the Professor used the candlestick to perform the nefarious deed in the library. We77 * should let the police take it from here.78 * </p>79 * 80 * <p>81 * BDDSoftAssertions works by providing you with proxies of the AssertJ assertion objects (those created by82 * {@link BDDAssertions}#then...) whose assertion failures are caught and stored. Only when you call83 * {@link BDDSoftAssertions#assertAll()} will a {@link SoftAssertionError} be thrown containing the error messages of84 * those previously caught assertion failures.85 * </p>86 * 87 * <p>88 * Note that because BDDSoftAssertions is stateful you should use a new instance of BDDSoftAssertions per test method.89 * Also, if you forget to call assertAll() at the end of your test, the test <strong>will pass</strong> even if any90 * assertion objects threw exceptions (because they're proxied, remember?). So don't forget. You might use91 * {@link JUnitBDDSoftAssertions} or {@link AutoCloseableBDDSoftAssertions} to get assertAll() to be called92 * automatically.93 * </p>94 * 95 * <p>96 * It is recommended to use {@link AbstractAssert#as(String, Object...)} so that the multiple failed assertions can be97 * easily distinguished from one another.98 * </p>99 * 100 * @author Brian Laframboise101 * 102 * @see <a href="http://beust.com/weblog/2012/07/29/reinventing-assertions/">Reinventing assertions</a> for the103 *      inspiration104 */105public class BDDSoftAssertions extends AbstractBDDSoftAssertions {106  /**107   * Verifies that no proxied assertion methods have failed.108   *109   * @throws SoftAssertionError if any proxied assertion objects threw110   */111  public void assertAll() {112	List<Throwable> errors = proxies.errorsCollected();113	if (!errors.isEmpty()) {114	  throw new SoftAssertionError(extractProperty("message", String.class).from(errors));115	}116  }117}...
