Software Testing

Is the absence of formal and independent QA affecting your product’s quality & stability?

Sometimes teams rely upon developers themselves testing the Software. While it initially is manageable and reduces the cost, as the product features expand testing becomes inadequate. As a result, the Software suffers from poor quality and it also consumes the developer’s precious time on an activity that can be and must be performed by an independent professional team.

Testing is not merely assuring oneself that the program works as designed. It is also to ensure that the Software does not do anything undesirable, works on multiple platforms, browsers and devices even under trying conditions. This requires a formal test environment and a professional independent team.

In QSG, we have a process driven, result oriented Software quality assurance approach that covers all stages of Software life cycle – initial discovery, development, deployment and maintenance. An approach that does not merely detect defects but also prevents their occurrence right from the initial stages of development.

A lean Agile process, experienced human resources backed by management’s commitment to quality ensure that the products undergoing QA emerge robust in quality. The QA approach helps implicit requirements become explicit, vague definitions become mutually understood terms and thereby assist the development team to address every detail of requirements.

As Software development runs on limited time and resources, the QA approach optimizes the efforts in such a way that serious and critical defects are detected early. Important Test cases are designed and executed early. The methodology ensures that all QA tasks remain relevant to short term and long term goals of development.

Our processes are agile enough to seamlessly integrate with the current development processes of the client. We can start QA with any kind of available input, be it nil formal requirements or highly structured ones. We can fit the QA into a sprint as short as one week. Our testing covers all aspects of Software – functionality, user interface, security, compatibility, performance etc. We provide testing on multiple operating systems, browsers, databases, mobile devices etc. We have experience testing applications on a variety of domains.

Automated Testing

The modern needs of Software test automation have become complex. A Software architecture that extends to multiple platforms, communication layers, devices and domain specific functional and security needs have made manual testing inadequate to test all nodes of Software functionality and performance. A true automation strategy must reach the critical areas of the Software, both seen and unseen, and discover defects or deviations. Not only the functionality that can be tested through user interface, but the backend – the backbone of Software architecture, must be tested through automation that does not rely upon user interface.

QSG uses project appropriate tools and techniques. Wherever standard tools are inadequate, we use custom scripting to enhance the automation coverage. Our automation test results are captured in such a way that they become source of information for developers to quickly diagnose the underlying problems.

Our automation strategy goes beyond automating test cases. It covers entire gamut of self-sustaining execution and reporting activity supported by Continuous Integration.

Mobile QA

The complexity of mobile native and hybrid apps is different from PC based apps. Multiplicity of vendors, devices and connectivity challenges result in incomplete and unsatisfactory user experience. Mobile Software QA must be aware of these ground realities. Our test laboratory is equipped with devices and capable of simulating many challenging connectivity environments apart from having know-how to perform both UI based and API level testing on Android and iOS ecosystem.

Our mobile R&D lab carries out in-depth, developer level mobile app analysis to find issues that are likely to affect mobile app functionality and performance.

Our immense skills on native and hybrid mobile app automation ensures that the apps are capable of providing delightful user experience in all usage situations. We use state-of-the-art tools and scripting techniques to test all critical nodes of app architecture.

 

Performance Testing

Gauge how well your applications respond to varying load conditions. Determine scalability thresholds using automated solutions.

The more the number of users on your application, the better it is for your business. The question is; can your application handle the growing number of users? Even more importantly, does the application respond to its users in quick time? We can help you find out exactly where the threshold lies.

How well does your system respond to user requests? Does it succumb to increasing load? How scalable is your system’s infrastructure in supporting your increasing client base? Do you have customers complaining that your system speeds irritate them during usage?

Very often, Performance testing is seen as a luxury & in many cases, a liability owing to the costs involved in regular performance testing activities. We believe that if a system has been designed to cater to the needs of multiple users/ multiple sets of users, it must respond to each of those users in a consistently timely manner. Speed & performance of the system cannot be compromised in the process of making the software feature-rich.

There need not always be complex mechanisms or expensive tools employed to monitor performance of your applications. Our simple automation solutions have even used open source functional automation tools like Selenium to effectively gauge application response times. Our experts have been involved in load testing as part of the services we offer to many of our customers over the years. Many of the applications we have tested for performance and load are being used extensively by thousands of simultaneous users to perform life critical operations on the field.

Load/ Scalability testing

Load testing deals with the quality of the application in the environment. The idea is to create an environment more demanding of the application than the application would experience under normal work loads. It is understood that if the application passes through this load, it will work under normal work loads. This is the hardest and most complex category of testing to accomplish. The right choice of tools/utilities is essential to ensure that load or stress related defects are appropriately identified.

Compatibility Testing

Change is inevitable, more so in the ever-evolving Software industry. With newer technologies, operating systems, browsers, devices, platforms etc. being introduced each day, it is imperative that Software applications adapt to these varying environments and conditions.

It is near impossible for development to create Software solutions that work in conformity with all environments. The onus is therefore on QA to identify compatibility flaws that make the Software unusable to end users.

It requires longer timeframes and a larger resource pool to test and certify that Software functions adequately under these complexities.

A combination of the best Software tools, latest devices and skilled testing teams ensure quicker turnarounds and more comprehensive compatibility test results for your applications that make them consistent across all usage platforms.

Security Testing

Security testing is vital for an application to guarantee that confidential data stays confidential indeed.

In this type of testing, QSG plays the role of the attacker and exercises the system in all possible ways using the most modern tools in an effort to find security related bugs. The goal of security testing is to identify threats in the system and measure its potential vulnerabilities. It also helps in detecting all possible security risks in the system and helps developers in fixing these problems in their coding.

Types of Security Testing:

There are seven main types of security testing as per Open Source Security Testing methodology manual. They are explained as follows:

  • Vulnerability Scanning: This is done through automated software to scan a system against known vulnerability signatures
  • Security Scanning: It involves identifying network and system weaknesses, and later provides solutions for reducing these risks. This scanning can be performed by both Manual and Automated methods
  • Penetration testing: This kind of testing simulates an attack from a malicious hacker. This testing involves analysis of a particular system to check for potential vulnerabilities to an external hacking attempt
  • Risk Assessment: This testing involves analysis of security risks observed in the organization. Risks are classified as Low, Medium and High. This testing recommends controls and measures to reduce the risk
  • Security Auditing: This is the internal inspection of Applications and Operating systems for security flaws. Audit can also be done via line-by-line inspection of code
  • Ethical hacking: Hacking an organization’s Software systems. Unlike malicious hackers who steal for their own gains, the intent here is to expose security flaws in the system
  • Posture Assessment: This combines Security Scanning, Ethical Hacking and Risk Assessments to show an overall security posture of an application

 

API Testing

Specialized API and web services testing for REST, SOAP and related protocols for faster, more accurate functional tests that do not involve your GUI.

Tests that do not involve the GUI not only run faster, exercise the functionality more thoroughly and are independent of completion of the user interface, they can also achieve test results that may be otherwise possible to accomplish using the GUI.

We have been performing manual as well as automated API tests for REST, SOAP and related protocols for several applications.

Data & Metrics

It is a cardinal principle of quality that ‘what cannot be measured cannot be improved’. A scientific testing methodology must generate and use measurable results. Our processes generate wealth of quantifiable data that are useful for understanding Test Coverage, traceability, stability, recurring issues and adequacy of testing. A data-driven testing and Software release would provide credibility of Software engineering process to both internal and external stakeholders.
