But an average salary range of Rs. 2.5 lacs to 5 lacs per annum. It keeps on increasing with your experience and expertise. All you need to do is opt for current Automation testing courses.

What is Manual Testing & How it Works?

manual-testingManual Testing refers to a mechanism in which a QA manually tests a software application. The testers look for defects in the software using a written test plan comprising various Manual testing interview questions. The effectiveness of Manual Testing is achieved when the tester steps into the shoes of the user.

For best results, the QA tester must have a detailed eye and a proactive approach. He analyses the behavior of a website or mobile app to check whether it delivers a different behavior than expected. If some discrepancies or defects are detected, the developer needs to replicate the bug.

Advantages of Manual Testing

– Only humans can gaze and evaluate the basic look and feel of the application or software. Most of the issues can be identified during this.

– A broader perspective of overall application is obtained by manual testing. It helps the tester to visually access text, layout, and other components.

– Manual Testing gives quick validation. It is easy for humans to observe, judge, and provide intuition.

– Some scenarios are bound to be done manually, for example, there are different software that behaves differently when automated or tested manually.

– It involves the low cost of operation.

Automation Testing refers to software testing activities executed via an Automation toolset or framework. It allows manual testers to focus on higher-value tasks. With Automation testing, greater test coverage can be achieved within a short time and with greater accuracy of results.

It involves writing test scripts that automate the execution. Investing manual effort is a wastage when it comes to regression testing. It is far more logical to program the machine to do the same with high speed and accuracy.

Advantages of Automation Testing

– Automated test execution is faster that improves the Testing coverage.

– It reduces the dependability of Testing on the availability of test engineers.

– It requires fewer resources for execution.

– It is more reliable due to reduced chances of error.

– Other activities performed by it include selecting the right product build, generating the right test data, and analyzing the result.
