Manual Testing is a process of finding out the defects or bugs in a software program. In this method the tester plays an important role of end user and verifies that all the features of the application are working correctly. The tester manually executes test cases without using any automation tools.
Automated testing tools are capable of executing tests, reporting outcomes and comparing results with earlier test runs. Tests carried out with these tools can be run repeatedly, at any time of day. The method or process being used to implement automation is called a test automation framework.
performance testing is in general, a testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload. It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as scalability, reliability
Mobile application testing is a process by which application software developed for handheld mobile devices is tested for its functionality, usability and consistency. Mobile application testing can be an automated or manual type of testing. Mobile applications either come pre-installed or can be installed from mobile software.
Cloud testing is the process of testing the performance, scalability and reliability of Web or mobile applications in a cloud computing environment. Testers can also scale application workloads to thousands or millions of concurrent users to find performance issues before the application goes live.
