java - 断言 try/catch block 未按预期工作

Question

当我运行 Selenium 脚本时，我使用的断言方法有点可以工作。当满足断言(元素存在)时，脚本将写入 xls 文件。如果不满足，脚本不会写入 xls 文件，并且会立即停止测试。

try {
                assertEquals(driver.findElement(By.xpath(prop.getProperty("failedlogin"))).getText(), "LOG IN");
                //add pass entry to the excel sheet
                testresultdata.put("4", new Object[] {
                    3d, "User should not be able to login with no password", "Login failed", "Pass"
                });
            } catch (Exception e) {
                //add fail entry to the excel sheet
                testresultdata.put("4", new Object[] {
                    3d, "User should not be able to login with no password", "Login failed", "Fail"
                });
            }

以下是我的 Excel 编写方法:

@BeforeClass(alwaysRun = true)
    public void setupBeforeSuite(ITestContext context) throws IOException {
        //create a new work book
        workbook = new HSSFWorkbook();
        //create a new work sheet
        sheet = workbook.createSheet("Test Result");
        testresultdata = new LinkedHashMap < String, Object[] > ();
        //add test result excel file column header
        //write the header in the first row
        testresultdata.put("1", new Object[] {
            "Test Step Id", "Action", "Expected Result", "Actual Result"
        });

    }

还有:

@AfterClass
    public void setupAfterSuite(ITestContext context) {
        //write excel file and file name is TestResult.xls 
        Set < String > keyset = testresultdata.keySet();
        int rownum = 0;
        for (String key: keyset) {
            Row row = sheet.createRow(rownum++);
            Object[] objArr = testresultdata.get(key);
            int cellnum = 0;
            for (Object obj: objArr) {
                Cell cell = row.createCell(cellnum++);
                if (obj instanceof Date) cell.setCellValue((Date) obj);
                else if (obj instanceof Boolean) cell.setCellValue((Boolean) obj);
                else if (obj instanceof String) cell.setCellValue((String) obj);
                else if (obj instanceof Double) cell.setCellValue((Double) obj);
            }
        }
        try {
            FileOutputStream out = new FileOutputStream(new File("C:/Users/matt_damon/workspace/project/passfail.xls"));
            workbook.write(out);
            out.close();
            System.out.println("Excel written successfully..");

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

那么，为什么即使我故意让测试失败，Excel 编写器也不写入失败条目？

检查 aseertEquals() 实际执行的操作。最有可能的是它抛出java.lang.AssertionError，它不是java.lang.Exception的子类。

这至少是 JUnit 的 Assert.assert*() 方法所做的事情。
