Test Optimization for Continuous Integration

“Test frequently and early.” If you’ve been following my testing agenda, you’re probably sick of hearing me repeat that. However, it is making sense that if your tests detect an issue soon after it occurs, it will be easier to resolve. This is one of the guiding concepts that makes continuous integration such an effective method. I’ve encountered several teams who have a lot of automated tests but don’t use them as part of a continuous integration approach. There are frequently various reasons why the team believes these tests cannot be used with continuous integration. Perhaps the tests take too long to run, or they are not dependable enough to provide correct results on their own, necessitating human interpretation.

Why Agile Is Great for Your Business

Agile project management is a great alternative to traditional methods, to address the customer’s needs and the delivery of business value from the beginning of the project. This blog describes the main benefits of Agile for both the customer and the business.

QA Management – Tips for leading Global teams

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.

How To Automate Mouse Clicks With Selenium Python

Sometimes, in our test code, we need to handle actions that apparently could not be done automatically. For example, some mouse actions such as context click, double click, drag and drop, mouse movements, and some special key down and key up actions. These specific actions could be crucial depending on the project context.

How To Handle Multiple Windows In Selenium Python

Automating testing is a crucial step in the development pipeline of a software product. In an agile development environment, where there is continuous development, deployment, and maintenance of software products, automation testing ensures that the end software products delivered are error-free.
