Top 3 Microservices Testing challenges with Ideal Solutions

Microservices is a successful attempt in Software development domain targeted at integrating specialized features. The benefits of microservices are comprehensive and businesses of all types can benefit from it. Some well-known benefits include scalability, flexibility, and deployability.

Software Testing Company

While microservices have several advantages, there are certain challenges that a company should be prepared for while testing and implementing microservices. This blog will discuss a few such challenges and also possible solutions for taking care of these challenges.

Phases

The right testing for microservices is best derived from Mike Cohn’s testing pyramid which involves unit testing, contrast testing, integrating testing, and E2E testing. These four phases involve a number of test in increasing order from unit testing having the highest number of tests preferably automated and E2E having the least numbers of tests; the time required to complete these phases depends on the number of tests.

The scope of testing also needs to follow the similar pattern. The E2E testing should have a minimum scope. The last phase should typically be limited to checking the working of all services together. Employing a third-party testing company would save your internal teams the hassles. Try to hire an offshore Software testing company to reap maximum benefits at competitive prices.

Challenges and Solutions

Unlike testing in other fields, microservices require specialized concerns. Each stage of testing might require a different strategy and one strategy would not work perfectly in every setting. Listed below are some challenges and solutions in microservices testing.

    Versatility: Though this looks like a benefit, it is more of a challenge because microservices are like small segments and companies deploy teams to take care of each segment. Now, the right type of testing would involve holistic and individual unit testing which becomes a challenge. Therefore, to take care of such a situation, the best approach is to streamline testing and decide which phase will have which kinds of test. For example, integration testing can be left for the last phase.

    Interoperability: This is another benefit and a testing challenge. All microservices are required to work in tandem with each other to create highly flexible Software. But, at the same time testing each of these individual features for working well with each other cannot be left till the last stage because rework would cost a lot to the organization. The solution is to keep cross checking with vital features as and when working so that last moment glitches can be avoided.

    Compatibility: Microservices are required to function in tandem with each other. They are sometimes required to be exposed to external APIs and these might cause issues in functioning at a later stage. This requires extensive testing because the behavior can be unexpected. The best solution, in this case, is to test all exposure in the intermediate stages ensuring that compatibility with external sources is maintained.

The challenges discussed above might all occur at once or can be visible like a glimpse. If your internal team is not confident then you can partner with offshore Software testing service providers at a nominal price. Looking at what microservices bring to the table, it is worth every effort put in testing and maintaining these strategies. The success derived from microservices is guaranteed if you have opted for an effective testing strategy that is versatile and robust.
