Selenium/java 返回空文本

Question

我有一个表格，下面是我正在为其编写 selenium 测试的 html 行的描述：

<mat-row _ngcontent-kgo-c23="" class="mat-row ng-star-inserted" role="row">
    <!---->
        <mat-cell _ngcontent-kgo-c23="" class="mat-cell cdk-column-id mat-column-id ng-star-inserted" role="gridcell">
            <a _ngcontent-kgo-c23="" ng-reflect-router-link="/dir,208" href="/claim/208">208</a>
        </mat-cell>
        <mat-cell _ngcontent-kgo-c23="" class="mat-cell cdk-column-firstName mat-column-firstName ng-star-inserted" role="gridcell">
        George
        </mat-cell>
</mat-row>

这是测试：

List<WebElement> idRows = super.wait(WAIT, INTERVAL).until(driver -> driver.findElements(By.className("mat-column-id")));
webDriver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
//Validate only one row exist in the search result
assertEquals(1,idRows.size());

//The result has is "208" and name "George"
WebElement firstNameInSearchResult = webDriver.findElement(By.className("cdk-column-firstName"));
System.out.println("===========>" + firstNameInSearchResult.gettext()+", " + idRows.get(0));
assertTrue(firstNameInSearchResult.getText().contains("George"));
assertTrue(idRows.get(0).getText().contains(searchId));

System.out.println 显示空文本。并且该打印语句之后的断言失败。我是否以正确的方式进行文本验证？

元素是Angular 元素。因此，要提取文本 208 和 George，您必须将 WebDriverWait 诱导为 visibilityOfElementLocated()，您可以使用以下任一 Locator Strategies：

• 打印文本208：

  • 使用 xpath 和 getAttribute("innerHTML"):

    System.out.println(new WebDriverWait(webDriver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//mat-cell[@class='mat-cell cdk-column-id mat-column-id ng-star-inserted']/a[contains(@ng-reflect-router-link, 'dir') and contains(@href, 'claim')]"))).getAttribute("innerHTML"));
    

• 打印文本George：

  • 使用 xpath 和 getText():

    System.out.println(new WebDriverWait(webDriver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//mat-cell[@class='mat-cell cdk-column-firstName mat-column-firstName ng-star-inserted']"))).getText());
