Web App Testing

Friday February 22, 2019

I have thoroughly tested my software, and it is now ready to be delivered to the clients? Hey but wait for a second! Have you also carried out an intrinsic round of backend testing?

NO! Then, we think you should take a while to read this article. 

With Software forming the base of almost everything in this new age world, computer applications are now becoming intricate.

With the increasing complexity of the front-end applications, the backend testing is too becoming complex.

Testing only the front end will not suffice in providing the customers with the best experience, and hence backend testing becomes very important

What is the Backend Testing?

Backend testing ensures that your application works fine at the server side and it assures the quality of the database.

The data that we enter in the front-end, is finally stored at the backend, using one of the many available databases like MySQL, Oracle, SQL server etc.

Assuring that the data we enter is properly and timely stored and retrieved from the database is done by backend testing. 

Importance of Backend Testing

Data is an important aspect of all computer applications. Most of the applications are loaded with a huge amount of data.

If you own a data hefty software, backend testing becomes very vital for you. Assuring that data is properly stored and retrieved when required is very important to assure the best Quality of your product.

Not only that, data security, accuracy, integrity, etc. are also major concerns of all the software.

Failing in either your software can fail miserably in the market. Backend testing also prevents complications like data corruption, deadlock, data loss, etc.

Pros of Backend Testing

Backend testing is an important part of software testing. The below given points will definitely justify its importance:

1.    Backend testing helps you test database, servers, and API.

2.    It detects bugs at an early stage thus reducing the cost of fixing them.

3.    Help you test your application more comprehensively, providing you complete control over the test coverage.

4.    Evade deadlock and data loss issues.

5.    Enhances the system’s functional constancy and sturdiness.

6.    Enhances data quality.

Cons of Backend Testing

Apart from having many benefits, backend testing does have some disadvantages. Here are few disadvantages of backend testing that you may incur:

•    To conduct manual backend testing you are required to have                    deep database knowledge.

•    It can add to your organizational cost.

Backend Testing Validation Mechanism:

Backend Testing includes validating Keys and Indexes, Sequences testing, data integrity testing, Stored procedures testing, Database server validations, Functions testing, Performance check, Database tables, Triggers, etc.

Skills Required For Backend Testing:

Being a backend tester, you should have a good knowledge of database concepts like normalization and SQL queries for backend testing.

Backend Testing Elements:

Depending upon the features of your application, backend testing may include many communication protocols, network configurations, database, servers, etc. 

Backend Database Testing

The database is an important part of your application. A seamless interaction between the GUI and the database is very important for the proper working of your application.

Any kind of discrepancies can cause performance bottlenecks and security issues. Hence Backend database testing is the most important. 

How to do Backend Testing?

Backend testing is no different from other types of testing and follows more or less the same procedure

•   Prepare a testing strategy, test plan, test cases and set up an                    environment.

•    Execute test plans.

•    Calculate the results.

•   Validate the results with anticipated results and the business                  requirements.

•    Report any defects or any issues.

For example, if we consider a train ticket booking website, it asks users to create their profile and also uses various online payment methods to book train tickets.

These websites use backend testing to assure the highest security and efficient working. The backend testing ensures that profile information like name, address, payment method, etc. are stored in their designated database tables and no information is missed.

A proper test should be carried out to ensure that the data are timely and correctly retrieved. For all the monetary transactions, ACID properties should be properly tested. 

Backend Testing Tools:

Backend testing is a time-consuming process and hence using the tools can reduce the work of testers to the minimum.

There are various tools available that support backend testing. Here are some of the commonly used backend testing tools.

•    Data Factory

•    Data Generator

•    Test Data Generator

•    AETG

•    TurboData


Through back end testing you can check the ACID properties, schema, etc. The most astounding feature of back end testing is that you don’t require the help of a GUI. You can directly inject data to the database with the help of a browser.

Database testing also helps in testing the business logic of an app. If you wish to know more about why your app needs and how it’s beneficial from a business perspective you can talk to us.
