I've needed this several times as well. I've put together a small sample below, which you'd want to adjust to your needs. Basically, you create your own Appender
and add it to the logger you want. If you'd want to collect everything, the root logger is a good place to start, but you can use a more specific if you'd like. Don't forget to remove the Appender when you're done, otherwise you might create a memory leak. Below I've done it within the test, but setUp
or @Before
and tearDown
or @After
might be better places, depending on your needs.
Also, the implementation below collects everything in a List
in memory. If you're logging a lot you might consider adding a filter to drop boring entries, or to write the log to a temporary file on disk (Hint: LoggingEvent
is Serializable
, so you should be able to just serialize the event objects, if your log message is.)

Web applications continue to evolve at an unbelievable pace, and the architecture surrounding web apps get more complicated all of the time. With the growth in complexity of the web application and the development process, web application testing also needs to keep pace with the ever-changing demands.
Hey Testers! We know it’s been tough out there at this time when the pandemic is far from gone and remote working has become the new normal. Regardless of all the hurdles, we are continually working to bring more features on-board for a seamless cross-browser testing experience.
The automation backend architecture of Appium has undergone significant development along with the release of numerous new capabilities. With the advent of Appium, test engineers can cover mobile apps, desktop apps, Flutter apps, and more.
People love to watch, read and interact with quality content — especially video content. Whether it is sports, news, TV shows, or videos captured on smartphones, people crave digital content. The emergence of OTT platforms has already shaped the way people consume content. Viewers can now enjoy their favorite shows whenever they want rather than at pre-set times. Thus, the OTT platform’s concept of viewing anything, anytime, anywhere has hit the right chord.
So, now that the first installment of this two fold article has been published (hence you might have an idea of what Agile Testing is not in my opinion), I’ve started feeling the pressure to explain what Agile Testing actually means to me.
