Do not use FOR statements in your tests

Sometimes, you need to assert that each value from a list is correct:

@Test
public void allProductNamesContainKeywordTest() {

   driver.get(HOME_PAGE_URL);
   Assert.assertEquals(driver.getCurrentUrl(), HOME_PAGE_URL);

   WebElement searchBox = driver.findElement(searchBoxBy);
   searchBox.sendKeys(KEYWORD);

   WebElement searchButton = driver.findElement(searchButtonBy);
   searchButton.click();

   wait.until(ExpectedConditions.urlContains(RESULTS_PAGE_URL));

   List<WebElement> productNames = driver.findElements(productNameBy);
   Assert.assertEquals(24, productNames.size());

   for (WebElement p : productNames) {

     String productName = p.getText();
     Assert.assertTrue(productName.toLowerCase().contains(KEYWORD));

   }

}

The test case implemented by this test method is very simple:

• opens the site

• searches for a keyword

• waits until the results page is displayed

• gets all product names displayed in the page

• asserts that there are 24 values in the product names list

• asserts that each product name contains the search keyword

The test case is simple but the test method can be simpler.

It would be simpler if it would not use the FOR statement.

How can we get rid of it?
