Which Software Tester Do You Need To Hire?
With technology being omnipresent and hyper evolving, it is important to keep your product at par with the industry standards. To achieve optimal performance from your product it thus becomes mandatory to grill it through various software testing services.
Therefore, it becomes equally important to choose the best-suited software tester who can understand the capabilities of your product and make it ready to release with optimal performance, accessibility or Automation Testing Services.
In this post, we will understand the little details of software testing and other things that can help you in choosing the appropriate service (software tester).
What exactly is software testing?
Put simply, it is a verification and validation process of a software application or program which: performs as expected and meets the technical & non-technical requirements of the business.
Comprehensive software testing services detect the flaws, errors, and loopholes in the application’s architectural code and then fix them. These errors are listed according to the severity, which is decided based on their design, development, and functioning.
The importance of a flaw is measured as to how it is affecting the performance, functionality, and usability of the application. It is often based on end user’s perspective for e.g. color scheme in a traffic signaling system may be of minimal or of no importance for average drivers and can be easily deployed during testing however the same color scheme is of paramount importance if the target user is a color-blind native.
Deploying the well-thought color scheme at this point gets importance. According to global data, 8% of all males & 0.5% of all females are color blind. To summarize the verification or software testing process confirms that the software meets its technical requirements while validation confirms that the product meets the business requirements.
Why software testing?
The object is to find bugs and loopholes. The sole motive of the business, software tester and programmer is to get a productive response by the usage of the software.
Software testing focuses on finding defects in the end-product. Software testing answers those following questions which general code reviews can’t, these are:
- Is the product working as expected?
- Is it meeting the requirements?
- Does it really work as expected?
- Are people liking it?
- Is it compatible?
- How is the performance?
- Is it allowing scalability?
- Is it ready to release?
Types of software testing
Automation is omnipresent. It simply means replacing human activity, ‘to an extent’, with systems, tools or devices in order to improve efficiency.
Automation saves the single most important and limited resource that is ‘time’. Cost-effectiveness and quality are lower in the priority list.
The goal of an automation software tester and software test automation is to test and compare the projected output with the actual output. The test is initiated by creating test scripts using automation testing tools of choice.
These tools can be chosen from a set of widely available open-source tools such as Selenium, JMeter, Appium and more. The software test automation is then used to automate the repetitive tasks which are otherwise difficult to perform manually.
Also, choosing the appropriate automation tool is of equal importance when it comes to comprehensive software test automation. The industry offers a plethora of open-source test automation tools and frameworks such as Cypress, Selenium, and Robotium.
Out of the lot, Selenium is the most preferred tool and has the ability to automate and run test parameters across various web browsers in different programming languages, namely Java, Python & C#.

Robotium testers can write automatic user acceptance, system tests, and functions for Android devices. While Cypress offers end-to-end integration along with the unit tests. It also allows access to distributed object models and provides a debugger.
The KRAs of performance testers does not revolve only around generating an artificial load, in fact, its about a lot more. Performance testing basically answers to these problem statements, including but not limited to, mentioned below:
- Getting stuck with legacy architecture
- Performance testing of the entire system
- Resolving complex tests
Performance computing about any product can be divided into 5 basic operational aspects, which are – algorithm, CPU, memory, storage & I/O. Measuring the performance of an application with reference to these gives the insight to determine whether your product is ready to be pushed to production.
The testing processes vary according to the priorities the tester sets in the test plan. A detailed test plan consists of the following subtests:
Load Testing – The load testing process efficiently utilizes modern-day testing techniques to reduce the overall time taken by the app, under a significant amount of increase in load, to process a command or operation. The team also rectifies any possible system bottlenecks and its solutions.
Endurance Testing – Also known as ‘Soak Testing’, is used to determine the performance or endurance level of the application under continuous load for an extended time period. This testing method helps in rectifying memory leak issues.
Spike Testing – This testing method determines the capability of the application when placed with sudden changes in the number of users on the system.
Volume Testing – The motive of the test is to find the amount of data that can be handled by the app. The volume testing process effectively evaluates the productivity of the app under an atmosphere of continuously increasing the volume of stored and processed data.
Stress Testing – This form of testing enables the engineer to check the resilience of the application, device, platform or network under extreme conditions such as overcapacity of users and system failures or crashes. These stress conditions reveal the loopholes that might cripple the software.
Scalability Testing – This is a non – functional testing method where the capability or the performance of the application is measured in terms of its capacity to scale up / down with the increase in processing power and altered architecture.
This, a comprehensive test plan helps in tracking all the vital statistics (Client, Server, and App) to optimize the performance of the app. Also, customized engineering frameworks help in strategizing the optimal performance improvements by integrating the exact technique and tool to give quality and achieve the best possible output.
Accessibility testing is an ongoing process that time, commitment and thorough knowledge along with a comprehensive approach.
Opting for skilled accessibility testers gives you several benefits over testers from different forte. They navigate pages without using a mouse, just as a person with a cognitive disability would do, use a variety of screen readers which converts text to audio.
They also use semi-automated tools to scan for compliance with ADA, Section 508 & WCAG 2.1. The accessibility tester thoroughly checks for the below-mentioned properties.
Page title – The tester looks for a page title that is unique, concise and meaningful. These titles are visible in tabs and bookmarks and must strictly relate to the page content.
Heading – This is done to check that the headings fit the page structure, provided they are of sound design. They also check for the accuracy and meaningfulness of the heading and whether it is correct or not, logically, with reference to the context. It needs to be in-sync with the page content.
Visual focus – While navigating the accessibility tester also looks for any unwanted change occurring while focussing on a certain element and vice-versa.
Forms – Forms are thoroughly inspected for appropriate and accessible labeling flagging and error messaging.
Leveraging the help of automated tools as well as manual testing is an integral part of the overall testing approach. Often when a sighted engineer is paired with a non-sighted engineer for accessibility testing it is known as a ‘Pair testing approach’. This comprehensive and detailed testing process impacts your journey towards complete accessibility.
Accessibility is not just a single step instead is an ongoing process that allows a more balanced and comprehensive approach to complete accessibility.
Whether it is performance, accessibility or automation choosing the appropriate tester completely depends upon what type of testing your product seeks, your budget allows and your infrastructure supports. Think well before opting!
