This is the second in a series of blog posts in which we outline the roadmap to TDD for your organization and how to choose the right experts for your projects. Find Part 1 here.
TDD works in very small increments of coding a test, writing the program code, and improving the code. This results in many (in fact hundreds) of automated small tests that need to be executed. This is not easy, especially when it comes to legacy code, proper unit test isolation, and other integration tests.
To ensure that the people you are going to bring on board have mastered that, you have to understand the factors to consider while collaborating with them.
Below are the important aspects that you should not ignore while hiring dedicated testers and QA team for projects based on the TDD process:
Technical and Analytical Skills of Business Analysts:
- Ability to analyze a set of techniques and tasks to be used to work as a liaison among stakeholders and recommend solutions that enable the organization to achieve its goals.
- Collecting requirements and analyzing how they’ll work as a product. And what will be the future problems they may face. According to that unit tests are defined and the acceptance criteria are defined for further development.
Technical Skills of Testers/Developers:
- Writing a unit test before writing the code and able to write code sufficiently to make a failing test pass.
- Expertise in “test-driven bug fixing”, i.e. when a defect is found, writes a test exposing the defect before correction.
- Knows and can name several tactics to guide the writing of tests (for instance “when testing a recursive algorithm, first write a test for the recursion terminating case”).
- Able to factor out reusable elements from existing unit tests, through using situation-specific testing tools.
- Creating a “roadmap” of planned unit tests for macroscopic features (and revising it as necessary).
- Ability to “test drive” a variety of design paradigms: event-driven, functional, and object-oriented; Also the technical domains like persistent data access, user interfaces, and computation.
Soft skills of QA manager:
- Communicate properly with non-technical as well as technical people, especially explaining the technical challenges to the management team.
- Understand the client provided specs and visualize a real-time business situation. He/She must also be ready for a knowledge-sharing session with either his/her team or higher management every time the situation arises.
- Must also have a strong programming base to keep up with their team w.r.t. understanding what the client needs.
How To Pick the Right Team?
Evaluate your company’s methodology: If you’re a startup or an established firm looking for an overhaul in methodologies, then it’s important to determine what type of team you prefer that can successfully collaborate with your company.
Check out websites and portfolios: A company’s website is the face you can judge it by. If the website works smoothly and the interface and user experience are user-centric, it means the company pays a great deal of attention to details.
Assess the testing experience of the team: It is important to find out what types of testing a team can provide in general; what approach the team applies in each particular case, and understand what tests the team has performed on specific projects.
Find out the industry focus of tested products: The quality assurance and testing team you hire needs to be experienced in testing apps or websites similar to yours.
Compare the size/complexity of the company’s projects with yours: The size/complexity of the project also matters a lot. If a QA team has worked only on simple projects, it may not be ready to step up on a large and more complex project and test it comprehensively.
Asking The Right Questions
In-depth questions will help you learn how they create and maintain quality assurance procedures, as well as filter out what meets your requirements. Here are some examples of questions you should ask:
– What will TDD give us that we can’t get by building tests later?
This question will help determine how well they understand and practice the benefits of TDD as mentioned above in the benefits section.
– What quality assurance and testing process do you use and why?
Gauge their understanding of QA processes and whether they have experience establishing these processes. This will also include the type of model they use to design the test plan.
– What are the best practices, automation toolkits, and testing methodologies the team employs?
This will enable you to understand the general testing approaches the team uses. Whether the team knows how to do automation testing, how they use automation testing, and with what tools they conduct it.
– Do you use TDD for accessibility concerns as well?
Since accessible features are getting a lot of attention, you can ask about their plans and involvement of accessibility concerns in your project. The concerns such as “does the correct ARIA hints are used for components?” and “is the correct semantic markup being used?” can be easily unit tested.
-How will you evaluate that testing was successful?
At this stage, specific expectations of testing may be revealed. Often, expectations don’t match that can be usually obtained through testing. In this case, it’s important to explain what exactly is impossible to do and why.
-What will be the format for bug reports and testing results?
This will help you agree on a specific format of bug reporting and testing results to ensure that you have all the information you need.
Collaboratively discuss the complete project with the team and clear all the queries that you may have in your mind. Remember to be transparent, honest, and open about everything. Define your budget prior. Use the opportunity to build a personal connection with the offshore development agency. This rapport will decide to work with you in a better manner.
Not only the Quality Assurance team, but you can also hire highly skilled developers, designers, testers, and digital product development experts.
