Error while running .getElementText() protocol action: This driver instance does not have a valid session ID (did you call WebDriver.quit()?) and may no longer be used. #4407
Description
Description of the bug/issue
I'm not sure if this issue is due to invalid syntax or if this should be valid, but if I try to check the placeholder text using syntax such as
browser.expect
.element('#searchbox_input')
.attribute('placeholder')
.text.to.equal('Search without being tracked');The test passes and also throws an exception
√ Expected element <#searchbox_input> to have attribute "placeholder" equal: "Search without being tracked" (18ms) Error Error while running .getElementText() protocol action: This driver instance does not have a valid session ID (did you call WebDriver.quit()?) and may no longer be used.
If I change the assertion to this format then I do not receive the error
browser.expect
.element('#searchbox_input')
.to.have.attribute('placeholder')
.which.equals('Search without being tracked');Steps to reproduce
Run the sample test
Sample test
import { NightwatchAPI, NightwatchTests } from 'nightwatch';
const localizationTests: NightwatchTests = {
before: () => {
browser.url('http://www.duckduckgo.com');
},
'Search input has placeholder text': (browser: NightwatchAPI) => {
// This passes, but then fails with the invalid driver instance error
browser.expect
.element('#searchbox_input')
.attribute('placeholder')
.text.to.equal('Search without being tracked');
// Works ok below
// browser.expect
// .element('#searchbox_input')
// .to.have.attribute('placeholder')
// .which.equals('Search without being tracked');
},
after: () => {
browser.end();
},
};
