java - 如何使 TestNG 报告显示软断言失败的行

Question

我正在使用 Selenium、Java 和 TestNG 编写测试。有时我在单元测试中使用了许多软断言，当它们失败时，TestNG 报告器不会显示它们发生的代码行。有没有办法让它显示出来？实际上，当我点击报告时，Failure Exception它会带我去，s_assert.assertAll();但我需要被带到特定的行，例如：s_assert.assertEquals(Alert_text, "Hi.. is alert message!", "Alert Is InCorrect");

Answer 1

以下自定义软断言的实现（我将其命名为验证器）应该可以满足您的要求。

import org.testng.annotations.Test;
import org.testng.asserts.Assertion;
import org.testng.asserts.IAssert;
import org.testng.collections.Maps;

import java.util.Arrays;
import java.util.Map;

public class SoftAssertExample {
    private Verifier verifier = new Verifier();

    @Test
    public void testMethod() {
        verifier.assertEquals(false, true);
        verifier.assertTrue(true);
        verifier.assertAll();
    }

    /**
     * A simple soft assertion mechanism that also captures the stacktrace to help pin point the source
     * of failure.
     */
    public static class Verifier extends Assertion {
        private final Map<AssertionError, IAssert<?>> m_errors = Maps.newLinkedHashMap();

        @Override
        protected void doAssert(IAssert<?> a) {
            onBeforeAssert(a);
            try {
                a.doAssert();
                onAssertSuccess(a);
            } catch (AssertionError ex) {
                onAssertFailure(a, ex);
                m_errors.put(ex, a);
            } finally {
                onAfterAssert(a);
            }
        }

        public void assertAll() {
            if (! m_errors.isEmpty()) {
                StringBuilder sb = new StringBuilder("The following asserts failed:");
                boolean first = true;
                for (Map.Entry<AssertionError, IAssert<?>> ae : m_errors.entrySet()) {
                    if (first) {
                        first = false;
                    } else {
                        sb.append(",");
                    }
                    sb.append("\n\t");
                    sb.append(ae.getKey().getMessage());
                    sb.append("\nStack Trace :");
                    sb.append(Arrays.toString(ae.getKey().getStackTrace()).replaceAll(",", "\n"));
                }
                throw new AssertionError(sb.toString());
            }
        }
    }
}

这是一个延迟的答案，但我想我会分享我的解决方案，因为我遇到了同样的问题。

下面打印出软断言的线路故障的位置。它显示了正在使用的类的方法内部的线路故障，如下所示：

1) 
Error: Custom error message goes here
[Class -> path.to.class.shows.here.ExampleClassName]
[Method -> exampleMethod]
[Line -> 342]

此解决方案的示例代码：

  public void assertIsTrueSoftly(String errorMsg, boolean condition) {
    String trace = null;

    if (!condition) {
      Throwable throwable = new Throwable();
      trace =
              String.format(
                      "[Class -> %s]%n[Method -> %s]%n[Line -> %d]",
                      throwable.getStackTrace()[1].getClassName(),
                      throwable.getStackTrace()[1].getMethodName(),
                      throwable.getStackTrace()[1].getLineNumber());
    }

    soft.assertThat(condition).withFailMessage(format("%nError: %s%n%s", errorMsg, trace)).isTrue();
  }

Answer 3

示例代码：

s_assert.assertEquals(Alert_text, "Hi.. is alert message!", "Alert Is InCorrect1");
s_assert.assertEquals(Alert_text, "Hi.. is alert message!", "Alert Is InCorrect2");
s_assert.assertEquals(Alert_text, "Hi.. is alert message!", "Alert Is InCorrect3");
s_assert.assertEquals(Alert_text, "Hi.. is alert message!", "Alert Is InCorrect4");
s_assert.assertall();

执行失败后它指向(s_assert.assertall();)行，同时它显示软断言失败的消息....

Alert Is InCorrect2
Alert Is InCorrect3

请检查输出。
