alertIsPresent() in protractor ?

• alertIsPresent() will verify whether alert is present or not.
• If alert is not present in given time then it will throw Time out error.

Please check below code script:

First write xpath with help of DOM

Navigate to https://keeplearners.blogspot.com/2018/03/Angular-elements.html

Here we have a Click Me button, when we click this button it will display browser alert.

describe('Protractor - waits - alertIsPresent()', function () {
    beforeAll(async function () {
        await browser.get("https://keeplearners.blogspot.com/2018/03/Angular-elements.html");
    });

    it('Code script to use waits - alertIsPresent in protractor', async function () {
        var EC = protractor.ExpectedConditions;
        var clickButton = element(by.css("button[ng-click='clickMe(angularAlert)']"));
        await clickButton.click();
        await browser.wait(EC.alertIsPresent(), 5000);
        await console.log("Alert is present");
    });
});

Output:

alertIsPresent() in protractor

Here we are giving time out 5000ms to verify whether alert is present or not.

If alert not present, it will display a time out error like below:

describe('Protractor - waits - alertIsPresent()', function () {
    beforeAll(async function () {
        await browser.get("https://keeplearners.blogspot.com/2018/03/Angular-elements.html");
    });
    it('Code script to use waits - alertIsPresent in protractor', async function () {
        var EC = protractor.ExpectedConditions;
        var clickButton = element(by.css("button[ng-click='clickMe(angularAlert)']"));
        await browser.wait(EC.alertIsPresent(), 5000);
        await console.log("Alert is present");
    });
});
