Software Testing Tutorial

Software testing is a process of finding bugs and defects in an application to make an application bug free and stable.

 “Checking the functionality of the application according to the customer requirements”.

To start testing:-

We should have requirements, application-ready, and availability of necessary resources.

To maintain accountability:-

We should assign a respective model to different test engineers.

It is a process of verifying the application and validates the product according to customer needs.

Software tester could be able to find the bug and defect to produce a good quality product.

The quality of a product depends on software tester that how many defects they can find and make the application bug free. To deliver a good quality product on time, we can use different types of software testing tools to make sure the quality of an application.

The Importance of Software Testing:-

1. Software testing is required to find out the error and defect that were made during the development stage of the application.

E.g., the developer made some mistake during the implementation phase of the Software, because of the less experienced and lack of knowledge in programming languages.

2. Software testing is necessary because customers like to have a good quality product which requires lesser maintenance cost and give effective results

E.g., suppose, If the customer does not find the testing organization trustable and not committed to deliver the quality of the product, then they might switch to an organization.

3. Software Testing is essential for a good and useful performance of Software applications.

4. Software tester has to ensure that an application should not result in any failures because it can lead to an increase in the cost of further releases.

5. Delivered a high-quality product or an application on a given time builds the customer’s trust and confidence in the organization.

6. Software testing plays a vital role to stay in business because some time product organization or small company which has less number of products and using low-quality software may lead to losses.

 Software testing can be done in two ways, i.e., Manual Testing and Automation Testing

  • Manual Testing:

When the application is tested manually without using any tools is known as Manual Testing.

  • Automation Testing:

When the application is tested with the help of some tools is known as Automation testing.

 Now a day’s most of the software testers prefer to do an automation testing because automation testing is time effective testing, while writing a test script we can see millions of data within minutes, having more accurate result and while performing the same task manually,  will take numbers of day and didn’t give the precise effect.
