Selenium WebDriver - two part - 1) Fail test on AssertEquals failure 2)Verify Element not present
提问by some_other_guy
I am back with more silly questions
我带着更多愚蠢的问题回来了
1) How to fail a test if AssertEquals is false?
1) 如果 AssertEquals 为假，如何使测试失败？
I have this code -
我有这个代码 -
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.
当宽度与预期值不匹配但测试用例通过时，此代码显示“宽度不正确”。如果宽度不相等，我希望测试失败。
2) How to assert/verify an Element is NOT present?
2) 如何断言/验证元素不存在？
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.
作为新手，我尝试了很多我在 Google 和 Stack Overflow 中找到的东西 - 使用 Selenium WebDriver 和 java 断言 WebElement 不存在，Selenium WebDriver - 测试元素是否存在等。但它们都不起作用。我正在使用 JUnit4 并且需要一个函数，如果元素不存在，该函数应该通过。
Thanks
谢谢

Answer 1: To use assert true or false you should use if else instead and then call the function by assert e.g.
答案 1：要使用 assert true 或 false 你应该使用 if else ，然后通过 assert eg 调用函数
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
然后AssertTrue(compareWidthPixels(by, expected))在测试中使用 compareWidthPixels 作为 ' '
Similarly for 2nd question you can use following
同样对于第二个问题，您可以使用以下内容
private boolean isElementPresent(By by) {
try {
driver.findElement(by);
return true;
} catch (NoSuchElementException e) {
return false;
}
}
using is element in assertions.
在断言中使用是元素。

Add Assert.fail();in your catch block.
添加Assert.fail();您的 catch 块。
Example:
例子：
try {
----- your code -----
} catch(Exception e) {
Assert.fail();
}
Hope this will solve your problem
希望这能解决你的问题
