Jasmine - Restart browser between tests (it blocks) - selenium-webdriver

Question

In our Protractor+Jasmine framework trying to restart browser between tests for different login user. As we have non-angular login page and after login its navigate to angular page. Following is my main test spec file
describe('User Permissions', function() {
var docsLoginPage = require('../pages/CLM_Page.js');
var projectsPage = require('../pages/Projects_Page.js');
var contentPage = require('../pages/Content_Page.js');
beforeEach(function() {
browser.ignoreSynchronization = true;
browser.get('http://be-docs-dev.xyz.local/');
});
it('Verify permissions for Non Admin and Read only permission group user', function() {
docsLoginPage.loginToDocs("sipqa4#xyz.com","Yahoo#123");
expect(browser.getTitle()).toEqual('abc');
browser.ignoreSynchronization = false;
expect(projectsPage.checkElementExistsById('headers_nav_projects')).toBe(false);
expect(contentPage.checkElementExistsById("content_browse_options_folder_settings")).toBe(false);
expect(contentPage.checkElementExistsById('content_browse_options_new_menu')).toBe(false);
});
it('Verify permissions for Project collaborator Non Admin and Read only permission group user', function() {
/*browser.restart().then(function(){
console.log("-----------Restarted the browser---------------");
});*/
docsLoginPage.loginToDocs("sipqa2#xyz.com","Yahoo#123");
expect(browser.getTitle()).toEqual('abc');
browser.ignoreSynchronization = false;
expect(projectsPage.checkElementExistsById('headers_nav_content')).toBe(false);
expect(contentPage.checkElementExistsById("projects_browse_options_folder_settings")).toBe(false);
expect(contentPage.checkElementExistsById('projects_browse_options_new_menu')).toBe(false);
});
});
And CLM_Page.js
var CLM_page = function() {
this.userName = element(By.id('userName'));
this.password = element(By.id('password'));
this.signIn = element(By.className('btn btn-primary'));
this.loginToDocs = function(userName, password) {
browser.driver.manage().window().maximize();
browser.driver.manage().timeouts().implicitlyWait(10000);
this.userName.sendKeys(userName);
this.signIn.click();
this.password.sendKeys(password);
return this.signIn.click();
};
};
module.exports = new CLM_page();
In conf file set to
restartBrowserBetweenTests: true
First it block is executing correctly. However while executing second it block browser restarting and closing immediately. Showing following error
Failures:
1) User Permissions Verify permissions for Project collaborator Non Admin and Read only permission group user
Message:
Failed: This driver instance does not have a valid session ID (did you call WebDriver.quit()?) and may no longer be used.
Stack:
NoSuchSessionError: This driver instance does not have a valid session ID (did you call WebDriver.quit()?) and may no longer be used.

Answer 1

The problem here is the webdriver session is closed after starting the test.
There is no problem with restartBrowserBetweenTests: true, Since your browser is restarted after the first test.
Since you are moving from non angular to angular application. Follow as below
browser.driver.get('http://localhost:8000/login.html');
browser.driver.findElement(by.id('username')).sendKeys('Jane');
browser.driver.findElement(by.id('password')).sendKeys('1234');
browser.driver.findElement(by.id('clickme')).click();
You are using browser.ignoreSynchronization = true; which is deprectaed. Try usingwaitForAngularEnabled(true).
make the BeforEach() as
beforeEach(function() {
browser.waitForAngularEnabled(false); // to tell protractor that this is a non- anularg page
browser.get('http://be-docs-dev.xyz.local/');
});
After moving to angular page make it as browser.waitForAngularEnabled(true);.
Hope the above answer helps you...

Based on your test case design, you can achieve the same by setting restartBrowserBetweenTests: false in conf.js file
And also clear the browser cookies and session from the browser after each it block run. Please modify your existing test script by adding afterEach
add the below snippet with existing code
afterEach(function () {
browser.manage().deleteAllCookies();
browser.executeScript('window.sessionStorage.clear();window.localStorage.clear();');
});
beforeEach function should be like
beforeEach(function() {
browser.waitForAngularEnabled(false);
browser.get('http://be-docs-dev.xyz.local/');
});
In conf.js.
Note: Default value is false. So it is not mandatory to set it as false
exports.config = {
...
restartBrowserBetweenTests: false,
...
}
If you are setting restartBrowserBetweenTests: true, This will cause your tests to slow down drastically. Please refer this
