retryWhen()
won't call repository.getObservable()
a second time. Instead, it takes the Observable.error()
that was returned the first time and resubscribes to it.
In order to use retryWhen()
in this way, you'd have to return a single Observable
that returns an error the first time it's subscribed to and does not do so in subsequent subscriptions. For example, you could do something like this:
Observable.defer(new Func0<Observable<String>>() {
boolean hasBeenSubscribedTo = false;
@Override public Observable<String> call() {
if (!hasBeenSubscribedTo) {
hasBeenSubscribedTo = true;
return Observable.error(new Exception());
}
return Observable.just("Hello, world!");
}
})
.retryWhen(/* ...etc... */)

With the rise of Agile, teams have been trying to minimize the gap between the stakeholders and the development team.
In 2007, Steve Jobs launched the first iPhone, which revolutionized the world. But because of that, many businesses dealt with the problem of changing the layout of websites from desktop to mobile by delivering completely different mobile-compatible websites under the subdomain of ‘m’ (e.g., https://m.facebook.com). And we were all trying to figure out how to work in this new world of contending with mobile and desktop screen sizes.
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.
The events over the past few years have allowed the world to break the barriers of traditional ways of working. This has led to the emergence of a huge adoption of remote working and companies diversifying their workforce to a global reach. Even prior to this many organizations had already had operations and teams geographically dispersed.
Software testing is fueling the IT sector forward by scaling up the test process and continuous product delivery. Currently, this profession is in huge demand, as it needs certified testers with expertise in automation testing. When it comes to outsourcing software testing jobs, whether it’s an IT company or an individual customer, they all look for accredited professionals. That’s why having an software testing certification has become the need of the hour for the folks interested in the test automation field. A well-known certificate issued by an authorized institute kind vouches that the certificate holder is skilled in a specific technology.
