What will come after “agile”?

I think that probably most development teams describe themselves as being “agile” and probably most development teams have standups, and meetings called retrospectives.There is also a lot of discussion about “agile”, much written about “agile”, and there are many presentations about “agile”. A question that is often asked is what comes after “agile”? Many testers work in “agile” teams so this question matters to us.

10 Best Software Testing Certifications To Take In 2021

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.
