A test script should have at least 1 assertion

If your test script does not have any assertions,

@Test
public void canNavigateToOtherPagesTest() {

   HomePage homePage = new HomePage(driver);
   homePage.open();

   ResultsPage resultsPage = homePage.searchBy(KEYWORD);

   resultsPage.goToPage(2);
   resultsPage.goToPage(3);
   resultsPage.goToPage(4);

}

then, you need to add at least one assertion to it.
