While Loop Conditions in Nightwatch.js

Nightwatch.js is a Node.js based end-to-end testing framework for web applications. It provides a simple syntax for creating custom test conditions using JavaScript. Here are a few examples of using while loop conditions in Nightwatch.js:

Wait for an element to be visible:

module.exports = {
    'Wait for element to be visible': function (browser) {
        browser.waitForElementVisible('#element-id', 5000, function (result) {
            if (result.value) {
                console.log('Element is now visible');
            } else {
                console.log('Element is still not visible');
            }
        });
    }
};

In this example, we're using the waitForElementVisible method from the Nightwatch API to wait for the element with the ID #element-id to be visible for up to 5 seconds. If the element is visible, the script logs a message to the console. If the element is not visible after 5 seconds, the script logs a different message to the console.

Wait for an element to be enabled:

module.exports = {
    'Wait for element to be enabled': function (browser) {
        browser.waitForElementEnabled('#element-id', 5000, function (result) {
            if (result.value) {
                console.log('Element is now enabled');
            } else {
                console.log('Element is still not enabled');
            }
        });
    }
};

In this example, we're using the waitForElementEnabled method from the Nightwatch API to wait for the element with the ID #element-id to be enabled for up to 5 seconds. If the element is enabled, the script logs a message to the console. If the element is not enabled after 5 seconds, the script logs a different message to the console.

Wait for an element to have a certain text:

module.exports = {
    'Wait for element to have text': function (browser) {
        browser.waitForElementPresent('#element-id', 5000, function () {
            browser.getText('#element-id', function (result) {
                if (result.value === 'Expected Text') {
                    console.log('Element has the expected text');
                } else {
                    console.log('Element does not have the expected text');
                }
            });
        });
    }
};

In this example, we're using the waitForElementPresent method from the Nightwatch API to wait for the element with the ID #element-id to be present for up to 5 seconds. Once the element is present, we're using the getText method to retrieve the text of the element and check if it matches the expected text. If the text matches, the script logs a message to the console. If the text does not match, the script logs a different message to the console.

These are just a few examples of using while loop conditions in Nightwatch.js. The framework provides many other methods for creating custom test conditions, so be sure to explore the Nightwatch API documentation to find the one that best fits your needs.
