JUnit
<testsuite name="CalculatorTests" tests="5" failures="1" errors="0" skipped="0">
  <testcase classname="CalculatorTests" name="testAdd" time="0.01"/>
  <testcase classname="CalculatorTests" name="testSubtract" time="0.01">
    <failure message="expected:&lt;5&gt; but was:&lt;3&gt;" type="AssertionError"/>
  </testcase>
  <testcase classname="CalculatorTests" name="testMultiply" time="0.01"/>

Which assertion correctly checks if the HTML report contains the summary of failed tests?
You have generated an HTML report from JUnit XML. Which assertion correctly verifies that the report contains the text showing the number of failed tests as 2?
JUnit
String htmlReport = "<html><body><div id='summary'>Tests run: 10, Failures: 2, Errors: 0</div></body></html>";
AassertEquals(htmlReport, "Failures: 2");
BassertTrue(htmlReport.contains("Failures: 2"));
CassertFalse(htmlReport.contains("Failures: 2"));
DassertNull(htmlReport);

Why does this JUnit XML report fail to show any test cases in the HTML report?
Given this XML snippet, the generated HTML report shows zero tests run. What is the likely cause?
JUnit
<testsuite name="SampleTests" tests="0" failures="0" errors="0" skipped="0">
</testsuite>
AThe <code>tests</code> attribute is zero, so no test cases are recorded.
BThe <code>failures</code> attribute should be greater than zero to show tests.
CThe <code>skipped</code> attribute must be set to zero explicitly.
DThe <code>errors</code> attribute is missing, causing the report to fail.

What is the main advantage of using XML reports for automated test results?
Why do automated testing frameworks often output test results in XML format like JUnit XML?
AXML reports reduce the test execution time significantly.
BXML reports are human-readable and require no additional tools to interpret.
CXML reports provide a standardized, machine-readable format that can be easily parsed and transformed into other formats like HTML.
DXML reports automatically fix test failures when parsed.
