Log4js appender suited for Protractor
What is it for?
Log4js is a very powerful tool to provide logs in a NodeJS application and/or test suite. Unfortunately, it poorly integrates with Protractor, as the latter uses a "control flow" system that runs tasks in a very particular order.
log4js-protractor-appender
ensures logging is integrated with the control flow, and display logging in the proper order.
Example:
logger.info('Navigating to /');
browser.get('/');
element(by.css('#someText')).getText().then(function (text) {
logger.info('Displayed text is: ', text);
});
logger.info('Should be displayed last');
Outputs without log4js-protractor-appender
:
[INFO] Navigating to /
[INFO] Should be displayed last
[INFO] Displayed text is: Some text
Outputs with log4js-protractor-appender
:
[INFO] Navigating to /
[INFO] Displayed text is: Some Text
[INFO] Should be displayed last
Promises
It resolves promises passed as arguments before outputting them.
Example:
logger.info('Displayed text is:', element(by.css('#someText')).getText());
Outputs without log4js-protractor-appender
:
[INFO] Displayed text is: [Promise object]
Outputs with log4js-protractor-appender
:
[INFO] Displayed text is: Some Text
Setup
log4js-protractor-appender
overrides log4js' default console appender. Just install it as a dependency:
$ npm install log4js-protractor-appender --save
Then you can load it as any console appender. For example:
{
"appenders": [
{
"type": "log4js-protractor-appender"
}
]
}
