Pretty good testing is easy to do. Excellent testing is quite hard to do.

Software testing and Quality assurance are the significant corner stones of software development. Software testing is evaluation of software against the requirements. It is also known as to run the software in the intention of finding bugs. A software bug is an error, flaw or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. Some bugs are less significant won’t cause any impact in the performance of the software, but few others lead to disasters. For example, in 1996 an unmanned Ariane 5 rocket launched by the European Space Agency exploded just forty seconds after its lift-off from Kourou, French Guiana. The reason behind disaster was a software exception caused during execution of a data conversion from 64-bit floating point to 16-bit signed integer value. So testing is an imperial task in software development life cycle, it should be carried out with proper attention.
In recent years, there has been a great evolution in the field of software testing with new trends coming into IT industry services. The introduction of new technologies has brought the latest updates in the software design, development, testing, and delivery. Along with the traditional testing techniques the tester must adopt new skills like DevOps and Scripless test automation. Now a major shift in this paradigm is testing the mobile apps. All online commerce and financial services are based on the mobile apps. So, testers are adopting new strategies like IOS App testing, Android app testing, Cloud-Based Mobile Application Testing Mobile Responsive Test etc.,
The technological changes are so rapid, that the tester should adopt the changes and invent new testing strategies to deliver a high-quality software product to the end user. So, tester should be an enthusiastic learner, develop skills in new technologies and invent new methodologies in software testing. The ultimate goal of the software testing is to provide satisfaction to the customer to delivering bug free software. Hence the software testing is an emerging area for young graduates to have a challenging career and platform to demonstrate their skills and knowledge.
