获取带有一些文本的按钮，然后单击量角器不起作用，为什么？

Question

I have a button with the text "Sim" on it, and I'm tryng to click on it, but proctactor can't find the element, why? It is on the screen.

HTML

 <button class="btn btn-primary" type="button">
              <i class="zmdi zmdi-check"></i>
                   Sim
            </button>

Test Code

element(by.partialButtonText('Sim')).click();

Error

Failed: element not visible

Answer 1

Check for visibility of button using protractor.ExpectedCondtions. You can use below code.

Code Snippet:

  var EC=protractor.ExpectedConditions;
  var buttonSim=element(by.xpath(".//*[contains(text(),'Sim')]"))

  browser.wait(EC.visibilityOf(buttonSim).call(),8000,'Button not visible');
  buttonSim.click();
