If you are facing issues selecting an md-tab (material tab) in Protractor, it could be due to various reasons. Here are some common solutions to help you select a material tab in Protractor:

  1. Use by.cssContainingText: Try using by.cssContainingText to find the tab based on its displayed text.

    typescript
    const tabText = 'Tab Text'; // Replace with the text of the tab you want to select const tabElement = element(by.cssContainingText('.mat-tab-label', tabText)); // Click the tab tabElement.click();
  2. Wait for Element to Be Clickable: Sometimes, Protractor tries to interact with elements before they are ready. Ensure you use appropriate ExpectedConditions to wait for the tab to be clickable.

    typescript
    const EC = protractor.ExpectedConditions; const tabText = 'Tab Text'; // Replace with the text of the tab you want to select const tabElement = element(by.cssContainingText('.mat-tab-label', tabText)); // Wait for the tab to be clickable and click it browser.wait(EC.elementToBeClickable(tabElement), 5000); // Wait for up to 5 seconds tabElement.click();
  3. Check if the Tab is Within an iframe: If the material tab is within an iframe, you'll need to switch to that iframe before interacting with the tab.

    typescript
    const tabText = 'Tab Text'; // Replace with the text of the tab you want to select const iframeElement = element(by.css('iframe')); // Replace with the appropriate iframe selector // Switch to the iframe browser.switchTo().frame(iframeElement.getWebElement()); // Find and click the tab const tabElement = element(by.cssContainingText('.mat-tab-label', tabText)); tabElement.click(); // Switch back to the default content after interacting with the iframe browser.switchTo().defaultContent();
  4. Check for Shadow DOM: Material tabs use shadow DOM, so you may need to access the shadow host before interacting with the tab.

    typescript
    const tabText = 'Tab Text'; // Replace with the text of the tab you want to select const shadowHost = element(by.css('mat-tab-group')); // Replace with the appropriate selector of the shadow host // Access the shadow DOM const shadowRoot = browser.executeScript('return arguments[0].shadowRoot', shadowHost.getWebElement()); // Find and click the tab inside the shadow DOM const tabElement = shadowRoot.element(by.cssContainingText('.mat-tab-label', tabText)); tabElement.click();

Ensure that you have correctly identified the tab using the appropriate selector and use the correct methods to wait for the element to be clickable before clicking it. If the tab is within an iframe or shadow DOM, make sure to switch to the relevant context before interacting with it.

By applying these strategies, you should be able to select the material tab successfully using Protractor.
