) => Awaitable<this, undefined | Error>;

A simple perform command which allows access to the Nightwatch API in a callback. Can be useful if you want to read variables set by other commands.
The callback signature can have up to two parameters. - no parameters: callback runs and perform completes immediately at the end of the execution of the callback. - one parameter: allows for asynchronous execution within the callback providing a done callback function for completion as the first argument. - two parameters: allows for asynchronous execution with the Nightwatch api object passed in as the first argument, followed by the done callback.

Waits for a condition to evaluate to a "truthy" value. The condition may be specified by any function which returns the value to be evaluated or a Promise to wait for.
An optional wait time can be specified, otherwise the global waitForConditionTimeout value will be used.

    ): Awaitable<this, null>;
};

Clear a textarea or a text input element's value. Starting with v1.1 clearValue() will wait for the element to be present (until the specified timeout).
If the element is not found, an error is thrown which will cause the test to fail. Starting with v1.2 you can suppress element not found errors by specifying the suppressNotFoundErrors flag.
Example 1
describe('clearValue Command demo', function() { test('demo test', function() { browser.clearValue('#login input[type=text]');
browser.clearValue('#login input[type=text]', function(result) { console.log('clearValue result', result); });
// with explicit locate strategy browser.clearValue('css selector', '#login input[type=text]');
// with selector object - see https://nightwatchjs.org/guide#element-properties browser.clearValue({ selector: '#login input[type=text]', index: 1, suppressNotFoundErrors: true });
browser.clearValue({ selector: '#login input[type=text]', timeout: 2000 // overwrite the default timeout (in ms) to check if the element is present });
});

**sendKeys** does not clear the existing value of the element. To do so, use **setValue()** instead.
An object map with available keys and their respective UTF-8 characters, as defined on [W3C WebDriver draft spec](https://www.w3.org/TR/webdriver/#character-types), is loaded onto the main Nightwatch instance as browser.Keys.
Example 1
// send some simple text to an input this.demoTest = function () { browser.sendKeys('input[type=text]', 'nightwatch'); }; // // send some text to an input and hit enter. this.demoTest = function () { browser.sendKeys('input[type=text]', ['nightwatch', browser.Keys.ENTER]); };

            result: NightwatchCallbackResult<null>
        ) => void
    ): Awaitable<this, null>;
};

An alias of "setValue" command, but hides the content from the nightwatch logs.
setValue/setPassword do not clear the existing value of the element. To do so, use the clearValue() command.
An object map with available keys and their respective UTF-8 characters, as defined on [W3C WebDriver draft spec](https://www.w3.org/TR/webdriver/#character-types), is loaded onto the main Nightwatch instance as browser.Keys.
Example 1
// send some simple text to an input this.demoTest = function (browser) { browser.setPassword('input[type=text]', 'nightwatch'); }; // // send some text to an input and hit enter. this.demoTest = function (browser) { browser.setPassword('input[type=text]', ['nightwatch', browser.Keys.ENTER]); };

method setValue

    (
        using: LocateStrategy,
        selector: any,

            result: NightwatchCallbackResult<null>
        ) => void
    ): Awaitable<this, null>;
};

Sends some text to an element. Can be used to set the value of a form element or to send a sequence of key strokes to an element. Any UTF-8 character may be specified.
From Nightwatch v2, **setValue** also clears the existing value of the element by calling the **clearValue()** beforehand.
An object map with available keys and their respective UTF-8 characters, as defined on [W3C WebDriver draft spec](https://www.w3.org/TR/webdriver/#character-types), is loaded onto the main Nightwatch instance as browser.Keys.
Example 1
// send some simple text to an input this.demoTest = function () { browser.setValue('input[type=text]', 'nightwatch'); }; // // send some text to an input and hit enter. this.demoTest = function () { browser.setValue('input[type=text]', ['nightwatch', browser.Keys.ENTER]); };

Sends some text to an element. Can be used to set the value of a form element or to send a sequence of key strokes to an element. Any UTF-8 character may be specified.
updateValue is equivalent with setValue and sendKeys with the exception that it clears the value beforehand.
An object map with available keys and their respective UTF-8 characters, as defined on [W3C WebDriver draft spec](https://www.w3.org/TR/webdriver/#character-types), is loaded onto the main Nightwatch instance as browser.Keys.
Example 1
// send some simple text to an input this.demoTest = function (browser) { browser.updateValue('input[type=text]', 'nightwatch'); };
// send some text to an input and hit enter. this.demoTest = function (browser) { browser.updateValue('input[type=text]', ['nightwatch', browser.Keys.ENTER]); };

        ) => void,

};

Opposite of waitForElementPresent. Waits a given time in milliseconds (default 5000ms) for an element to be not present (i.e. removed) in the page before performing any other commands or assertions. If the element is still present after the specified amount of time, the test fails.
You can change the polling interval by defining a waitForConditionPollInterval property (in milliseconds) in as a global property in your nightwatch.json or in your external globals file. Similarly, a default timeout can be specified as a global waitForConditionTimeout property (in milliseconds).
Example 1
module.exports = { 'demo Test': function() { // with default implicit timeout of 5000ms (can be overwritten in settings under 'globals.waitForConditionTimeout') browser.waitForElementNotPresent('#dialog');
// specify the locate strategy (css selector/xpath) as the first argument browser.waitForElementNotPresent('css selector', '#dialog');
// with explicit timeout (in milliseconds) browser.waitForElementNotPresent('#dialog', 1000);
// continue if failed browser.waitForElementNotPresent('#dialog', 1000, false);
// with callback browser.waitForElementNotPresent('#dialog', 1000, function() { // do something while we're here });
// with custom output message - the locate strategy is required browser.waitForElementNotPresent('css selector', '#dialog', 'The dialog container is removed.');
// with custom Spanish message browser.waitForElementNotPresent('#dialog', 1000, 'elemento %s no era presente en %d ms');
// many combinations possible - the message is always the last argument browser.waitForElementNotPresent('#dialog', 1000, false, function() {}, 'elemento %s no era presente en %d ms'); },
'demo Test with selector objects': function() { browser.waitForElementNotPresent({ selector: '#dialog', timeout: 1000 });
browser.waitForElementNotPresent({ selector: '#dialog', locateStrategy: 'css selector' }, 'Custom output message');
browser.waitForElementNotPresent({ selector: '.container', index: 2, retryInterval: 100, abortOnFailure: true }); }
'page object demo Test': function () { var nightwatch = browser.page.nightwatch(); nightwatch .navigate() .assert.titleContains('Nightwatch.js');

Opposite of waitForElementVisible. Waits a given time in milliseconds (default 5000ms) for an element to be not visible (i.e. hidden but existing) in the page before performing any other commands or assertions. If the element fails to be hidden in the specified amount of time, the test fails.
