In the software development life cycle (SDLC), testing is the phase where developers check whether the software satisfies the specific requirements, needs, and expectations of the customer by testing for bugs, defects, and errors. Testing tools help testers to find issues in their products before the users do, ultimately resulting in better quality software.
Testing typically involves manual testers, automation engineers, and developers. There are many types of testing, some of which include: unit testing, integration testing, functional testing, performance testing, regression testing, acceptance testing, and usability testing. Some tools focus on just one category, while others provide comprehensive coverage. Testing can also be divided into two categories based on transparency:
White Box Testing:
This is a software testing method that involves testing the internal structure, design, and coding of a piece of software. Specifically, it tests for things like internal security holes, broken paths in the coding process, the flow of specific inputs through the code, expected output, and functionality of conditional loops. Code is visible to the tester, which is where the “white box” or “see-through box” concept comes from. White box testing is also known by a variety of other names, such as Clear Box Testing, Open Box Testing, Transparent Box Testing, Code-Based Testing, and Glass Box Testing.
Black Box Testing
Black box testing also involves testing the internal structure, design, and coding of software. It is distinguished from white box testing in that the internal design of the software is not known to the tester, and is therefore a “black box”. Its goals are to find incorrect or missing functions, interface errors, errors in data structures or external database access, behavior or performance errors, and initialization and termination errors. It is usually categorized as functional testing and can also be called Behavioral Testing.
Within the modern testing sphere, shift-left and automation are two concepts that are becoming increasingly important.
Shift-left is the practice of testing earlier in the software delivery process. Rather than deferring thorny issues to an unknown later date, testers can improve quality by catching errors before they snowball or become critical. Shift-left focuses mainly on integration testing and identifying integration issues as soon as possible.
Test automation is done through a special software tool separate from the software being tested. It allows testers to reuse tests in a repeatable process, thereby eliminating time-consuming and repetitive tasks. These tests can also be run overnight, which saves time for all involved. Generally, test automation is considered to be critical for agile development, CI/CD, and DevOps. Despite that, it is not always appropriate to automate all testing in an organization, and many organizations perform both automated and manual testing.
Looking ahead to the future, artificial intelligence (AI) and machine learning (ML) may play a key role by allowing organizations to automate even further.
Testing tools support test activities such as requirements, planning, test execution and automation, and defect logging.
When selecting the appropriate testing tool for your organization, there is no one tool that does it all. It is important to compare features and evaluate requirements, such as:
1. Which platforms are covered?
2. Which scripting languages are covered?
3. Are programming skills required, or can a layperson operate the tool?
4. Ease of installation and setup
5. User interface
6. Object storage and maintenance
7. What integrations are available?
8. Product support and documentation
9. Licensing and cost
In regards to automated testing, it is particularly useful for static and repetitive tests that don’t change from one test cycle to the next. Regression testing, smoke testing, data-driven testing, and performance testing can all benefit from automation.
Testing tools ensure that businesses are shipping the best possible product to the end user. Automated testing confers certain benefits, such as: time saved, improved quality, early bug detection, 24/7 testing, reusability, distributed test execution, robust reporting, improved test coverage, better employee utilization, less room for human error, increased collaboration, and improved ROI.
In certain industries, such as medical devices, test details must be documented in a regimented process. Test management tools can automatically keep a log of those details for compliance purposes. For companies that release multiple times a day, such as Amazon and Netflix, automated testing is an absolute necessity.
Ranorex Studio is a commercial Windows GUI test automation framework used to test desktop, web-based, and mobile applications. It is built on Microsoft’s .NET platform and supports C# and VB.NET. Its key features include easy installation for non-programmers, image recognition, recording and replay, data-driven and keyword-driven tests, cross-platform and device testing, and reports and logs.
Ranorex Studio is a premium, powerful testing tool that is more comprehensive and also more expensive than many other tools in its category. It is a good solution for implementing automated testing in continuous delivery and DevOps environments.Visit Website
SoapUI is a free and open-source test automation framework for APIs like SOAP and REST. Its functionality includes web service inspection, invoking, development, simulation and mocking, functional testing, load and compliance testing. It is also offered as a paid pro version, which has advanced features like test history, SQL query builder, and enhanced support.
SoapUI’s strengths are its easy setup, well-designed user interface, and breadth of integrations. It is simple to learn and operate even for non-technical users. However, it can be slow and the free version lacks important features like version control.Visit Website
Katalon Studio is a free automation testing tool that is powered by Selenium. It is designed to create and reuse automated test scripts for UI without coding, and allows for the testing of UI elements like pop-ups, iFrames, and wait time. Compared to Selenium, Katalon is easier to deploy, offers more integrations, and has features for analytics and reporting. It is extremely easy to set up and works immediately out of the box. However, it is not open source and its community is small, so support may be limited. It is best characterized as an emerging solution that works for small and medium size businesses.Visit Website
ThreatModeler is an enterprise-level automated threat modeling platform that utilizes VAST (Visual, Agile and Simple Threat Modeling) methodology, is PFD-based, and identifies threats based on a customizable comprehensive threat library. It takes a proactive approach to identifying entry points to prevent security breaches in applications and computer systems. Distinguishing features include process flow architecture diagrams, a centralized and customizable threat library, and an intelligent threat engine. Unlike most other threat modeling tools, ThreatModeler has a plethora of cloud-friendly features.Visit Website

Created in 2005, Rspec is a testing framework for behavior-driven development (BDD) for Ruby. It allows you to conduct Unit, Functional, and Feature tests. RSpec is composed of multiple libraries, which are designed to work together, or can be used independently with other testing tools like Cucumber or Minitest. It is one of the most frequently used testing libraries for Ruby in production applications.
Rspec features a simple syntax that reads more like English than your typical code. Like all Ruby related tools, it is available in the form of the RSpec Ruby gem, which makes it easy to install.Visit Website
SpecFlow is an open source testing framework that supports Behaviour Driven Development (BDD). As part of the Cucumber family, SpecFlow uses the official Gherkin parser and supports the .NET framework, Xamarin and Mono.Visit Website
