Selenium WebDriver - 两部分 - 1）对AssertEquals失败的失败测试2）验证元素不存在

Question

I am back with more silly questions

1) How to fail a test if AssertEquals is false?

I have this code -

public boolean compareWidthPixels(By by, String expected) {
    System.out.println(driver.findElement(by).getCssValue("width"));
    try {
        assertEquals(expected, driver.findElement(by).getCssValue("width"));
        System.out.println("Width as expected");
        return true;

    } catch (Error e) {
        verificationErrors.append(e.toString());
        System.out.println("Width incorrect");
        return false;

    }

This code displays "Width incorrect" when the width does not match the expected value but the test case passes. I want the test to fail if the width are unequal.

2) How to assert/verify an Element is NOT present?

As a novice I tried many things I found in Google and here in Stack Overflow - Assert that a WebElement is not present using Selenium WebDriver with java , Selenium WebDriver - Test if element is present , etc. But none of them worked. I am working with JUnit4 and need a function that should pass if the element is not present.

Thanks

Answer 1

Answer 1: To use assert true or false you should use if else instead and then call the function by assert eg

public boolean compareWidthPixels(By by, String expected) {
    System.out.println(driver.findElement(by).getCssValue("width"));
    if (driver.findElement(by).getCssValue("width").equals(expected)){
        System.out.println("Width as expected");
        return true;
    } 
    System.out.println("Width incorrect");
    return false;
}

Then use compareWidthPixels as ' AssertTrue(compareWidthPixels(by, expected)) ' in your test

Similarly for 2nd question you can use following

private boolean isElementPresent(By by) {
    try {
        driver.findElement(by);
        return true;
    } catch (NoSuchElementException e) {
        return false;
    }
}

using is element in assertions.

Answer 2

Add Assert.fail(); in your catch block.

Example:

try {
    ----- your code -----

} catch(Exception e) {
    Assert.fail();
}

Hope this will solve your problem
