Automated and manual software testing for business processes automation

Software testing is a critical factor for the successful development and implementation of the business processes

One of the main purposes of the developers and testers, as well as the company’s headquarters, is to accelerate the process of software testing and applications’ debugging, increase test coverage and testing performance within the IT budget reasonable scale.

According to the degree of automation, the following types of software testing are distinguished: 

• Manual testing – involves writing test cases by the testers and manually checking all the scenarios before the software release.
• Automated testing – involves special software to perform testing and verification of the testing results, which helps to reduce testing time and simplify the testing process.

QA Automation has several advantages over manual testing; it allows:

• Verify the implementation of all business processes in the shortest time
• Increase the accuracy and effectiveness of the testing process. Accuracy and repetitiveness of the testing process lead to the early detection of most defects
• Compatibility

Examples of PNN Soft Company’s successful projects using automated testing:  

• Remittances (sending and money paid to various money transfer systems (MoneyGram, Ria, Anelik, etc.);
• Credit systems (creation and processing of loan applications);
• Budget management system (creation and processing of applications);
• Other customer projects.

While these projects implementation, we are using automated testing, which allows us to reduce the time spent on the creation of the same requests 2 – 3 times. QA automation plays a key role in increasing the speed, efficiency and flexibility of the software testing process. As a result, defects are detected early and resolved quickly.

We use special software in the testing process:

Selenium WebDriver – an automated tool for functional and regression testing. This tool has special drivers customized for a specific web browser. That means Selenium WebDriver works with every browser individually. This increases the stability of the test performance as they are adjusted for a specific browser. Moreover, it becomes easier to write tests and maintain them. Test performance increases. Selenium WebDriver uses the native command, i.e. is trying to copy the user’s actions completely. At the moment, the following drivers are available: FirefoxDriver; InternetExplorerDriver; ChromeDriver; AndriodDriver – mobile browser, and IphoneDriver – mobile browser. Languages list supported by Selenium WebDriver: C#, Java, Ruby, Phyton.

Jakarta JMeter – a tool for load testing, testing server loading when handling a large number of users.

In most projects, we test the user interface (GUI testing), which involves stimulation of the user activity.

During the testing, we used two basic approaches:  

Simulation Utilities. Selenium IDE tool for Mozilla Firefox, which records the user’s activity and then performs it while testing. At the same time, any small change in the software being tested requires a rewrite of manual tests.

Scripting – a form of programming on languages (mainly in Java) specially designed for software testing automation, which simplifies the time point of the code change while changes in web applications.

PNN Soft pnnsoft.com proposes QA and functional testing in the following variants:

• an integral part of the custom software development process
• independent QA and testing outsourcing service  
• an independent system, architecture and code audit service

The proposed methods cover manual and automated testing. Within white box testing, our specialists perform revision and testing of the standalone web applications, client-server systems and embedded devices functionality, language-specific Java, C#, and C++.
