Let us go.
A Brief Understanding of Test Automation In Agile and Scrum Environments
In the Agile and Scrum environments, development cycles are slashed into short, time-limited sprints, each yielding accumulative assistance to the software. While this iterative procedure facilitates rapid evolution, it simultaneously offers the challenge of maintaining uncompromised quality. Automation testing emerges as a pivotal enabler, functioning as a fortress against defects and regressions while facilitating teams to maintain an unswerving cadence of innovation.
By automating critical and routine test cases, Agile teams attain a competitive edge characterized by quicker feedback loops, an impenetrable shield of validation, and curtailed manual testing endeavors. For instance, let’s consider a real-world scenario. A multinational e-commerce platform is working towards improving its search feature, striving to provide customers with a seamless experience while discovering products. During each sprint, new search algorithms are introduced with the goal of enhancing both the accuracy and speed of the search capabilities.
Automated testing validates these algorithms, assuring that search outcomes remain accurate and appropriate products are presented to customers. Automated testing is crucial to maintain the accuracy of search results and furnish a seamless shopping experience to customers amidst the frequent algorithmic changes. Failing to execute automated testing can lead to inaccurate results, which could negatively impact customer satisfaction. Consequently, it is imperative to prioritize automated testing to guarantee consistent and reliable performance.
What Should Be Automated In Agile and Scrum Environments?
As organizations strive to keep up with varying market demands, they are turning increasingly to Agile and Scrum methodologies to help them deliver high-quality products quickly. Nonetheless, to comprehensively realize the benefits of these methodologies, it is essential to automate certain aspects of the software development lifecycle. Automation can authorize teams to work more efficiently, diminish errors, and raise productivity. But what precisely should be automated in an Agile or Scrum environment?
Providing a clear-cut answer to this question is challenging, as different teams may have differing demands and requirements. Here are a few key areas of Agile and Scrum that can benefit from automation:
Builds and Deployments
In conventional environments, there are predefined builds that can be every week, fortnightly, or occasionally even monthly. This is the reason why these deployments take time. One drawback of this approach is the necessity for developers to adhere to predetermined dates for resolving bugs or implementing new features, resulting in delays.
The second reason pertains to the issue that arises when testers identify bugs and defects after completing the testing phase while programmers have already progressed to other parts of the implementation process. As a result, they may exhibit less interest in resolving the defects of the previously implemented application. This process also hinders the time required to make the feature available in the production environment.
The building and deployment can often be perceived as repetitive and unexciting. Furthermore, it can take hours to deploy a build. This delays testing and ultimately, feedback.
Below are a few of the benefits of automated build deployment:
- No possibility of making deployment errors
- Once a bug or feature has been fixed, it becomes available for testing immediately
- Testers get more time to test features
- The functionality is prepared for deployment to the production environment within a shorter time frame
- Quick feedback
Component Tests/ Unit Tests
The foundation or base of any construction needs to be rock solid. The same goes for test automation. Component tests and unit tests constitute the lower layer or foundation of the pyramid. The development team should collaborate and work cohesively to acclimate the majority of the tests into this layer.
API/Web Service Testing
Web services promote the exchange of data or information between two applications through a request and response mechanism without delving into the underlying architecture or technology. In simple terms, delivering a request and verifying the response is usually done in web services testing. This process stimulates a thorough evaluation of the service’s functionality and performance.
To perform thorough testing of a web service, it is essential to develop programs that specifically interact with the web service methods and confirm the accuracy and validity of the returned values. Furthermore, services for various permutations and combinations can also be tested. The test data has been compiled and organized in an Excel sheet for convenience. The program can efficiently access and utilize this data by calling the testable service while providing the test data as a parameter. This process ensures the accuracy of the results through thorough validation.
Web service testing acts as the middle layer of the testing pyramid. The majority of functional testing can be efficiently conducted within this layer. Addressing and resolving any defects that arise in this layer becomes a streamlined process, eradicating the need to postpone these issues until the UI is available.
Data Comparisons
Various tests necessitate comparing data files, including CSV files, Excel files, or text files.
- These files can be compared against baselines to perform data validation.
- Data comparisons can occur when identical data is presented in different formats. This commonly arises when two identical files are generated from different sources.
Automating these comparisons can result in increased efficiency by eliminating repetitive tasks.
Testing Behind the GUI (Graphical User Interface)
Automating the testing process underlying the graphical user interface is relatively simpler than automating the graphical user interface itself. Another benefit is that irrespective of the user interface (UI) modifications, functionality remains intact. Although there may be alterations to certain user interface components, the fundamental operation of the feature remains unaltered. This technique primarily focuses on business reasons and rules.
The test cases are typically written in a tabular or spreadsheet format. Corresponding fixtures and code snippets are created to accept input from these tables and generate results immediately. The results offer a robust and user-friendly platform for non-technical stakeholders to conduct tests and obtain accurate outcomes.
Searching
Locating a specific entity within a sizable collection of files can be a time-consuming and laborious process, especially if it is a recurring task. An instance of this type of task is searching through log files. To streamline this process, it may be worthwhile to consider automating it.
Repetitive Tasks
When dealing with tasks that involve interacting with end-users or writing stories for their development, it is advisable to consider automation if they are repetitive in nature. Taking this approach can optimize efficiency and free up valuable time for more important tasks. It is crucial to understand that performing test automation doesn’t imply that there needs to be a sophisticated tool or technology involved in it. A possible solution to the problem could be to develop either a Visual Basic macro or a Java program incorporating Javascript.
Tips to Maximize Test Automation in Agile and Scrum Environments
Maximizing test automation can be complicated, even for experienced Quality Assurance testers. Below are a few tips to integrate test automation into the agile and scrum environment:
Understand What Software Sequences to Automate
While some requirements may be more intricate and demand a nuanced approach, many can be effectively met with a binary outcome, such as a simple yes or no. To ensure the accuracy of the system’s performance, it is crucial to prioritize the development of automated test scripts that address the following inquiry: Does the system execute this task or exhibit this feature correctly?
It is imperative to emphasize this aspect in testing procedures to maintain optimal functionality and end-user satisfaction. Developing appropriate test scripts for specific scenarios enables accurate feedback and optimizes time management when high reusability is required.
Conduct Sequence Testing with Development
Agile methodology employs sprints as a means to divide a large and intricate software development process into smaller, attainable objectives. Proactively plan and prepare automated test scenarios to coincide with the development of new features within the same sprint. This approach will significantly improve the speed and relevance of feedback while also minimizing the risk of costly rework at a later stage.
Select the Right Test Management Tool
Modern test managers can leverage test management tools to facilitate the laborious administrative tasks of test management, which include creating test cases and consolidating tester feedback. Also, contemporary test management platforms can integrate with other project management and software development tools. This will help to facilitate the management of numerous development projects and make collusion during testing intuitive.
