Microservices Testing: The Essence

Microservices testing is a combination of QA activities to ensure each microservice’s functioning and performance is stable, its failure doesn’t result in severe functional disruptions of entire software, all microservices smoothly function as one application.

  • Microservices testing types: multi-level functional testing, regular regression testing, performance and security testing.
  • Microservices testing team: a QA manager, manual and test automation engineers, a test automation architect.

ScienceSoft provides a full scope of microservices testing activities from high-end consultancy to professional microservices testing to ensure maximum quality of customers’ software.

Microservices Testing Setup Plan

A microservices testing setup plan depends greatly on the current SDLC stage of your microservices project and the software requirements specifics.

Still, based on ScienceSoft’s portfolio of microservices testing projects, we can outline some universal steps to follow.

1. Microservices testing process design

Duration: Up to 1 week

  • A QA manager should be assigned to ensure the testability of your microservices software requirements.
  • A set of KPIs relevant for testing microservices should be drawn up. You can consider such KPIs as the number of defects found and test cases/scripts developed per iteration, test cases’ granularity, test scripts’ maintainability and robustness, etc.
  • A risk mitigation plan also should be designed to oversee the relevant risks of your microservices testing project.

Best practice: As every microservice is developed and deployed independently, ScienceSoft usually integrates a test engineer into each cross-functional microservice team and establishes collaboration scenarios between the test engineers for better coordination and prioritization of the testing activities.

2. Microservices testing preparation

Preparation for the microservices testing process differs based on the sourcing model you opt for: in-house testing or outsourced testing.

2.1. In-house microservices testing preparation

Duration: Up to 4 weeks

If you opt for an in-house microservices testing option, your QA manager should:

  • Prepare a test strategy, plan, and efforts estimation (typically, a test engineer is assigned to each microservice, still sometimes more test engineers may be required depending on the microservice architecture and functionality complexity).

Best practice: ScienceSoft’s QA consultants usually opt for test automation in a microservices testing project as the microservices-based architecture fits test automation well.

  • Assemble a test team, hire test automation talents experienced in microservices testing and consider additional training for test engineers.

While a test automation manager should:

  • Consider what test scenarios are repeatable, stable, and involve a high data volume to be automated first. Design a test automation architecture.
  • Choose and configure relevant tools and frameworks for automated testing.
  • Decide on service virtualization and API mocking tools essential for testing microservices.

NB! ScienceSoft’s QA consultants advise to check if the following software testing types vital for microservices testing are well-represented

Integration, component, contract testing

The testing team should develop and execute:

  • Integration test cases (validating communication paths and interactions between components within each microservice).
  • Component test cases (verifying a microservice behavior with the help of API mocking tools).
  • Contract test cases (checking the real communication between microservices).

These testing types should comprise the majority of microservices test suites.

It should include load, stress, endurance, and scalability testing at both:

  • Microservice level (when a microservice is deployed).
  • Application level (when all the microservices are deployed).

Regression testing

To avoid application breakdowns upon introducing new services or API evolution, a test engineer within each microservices team should verify how their microservice interacts with its dependencies.

Expert tip: ScienceSoft’s test automation managers strongly recommend automating the regression test suites for all microservices, as the number of regression test cases to be performed per iteration can be multiplied by the number of microservices. Besides, a comprehensive regression test suite for entire software should be run each time a new microservice is deployed.

2.2. Vendor selection for outsourced microservices testing

Duration: Up to 12 weeks

If you decide to outsource your microservices testing, during a testing vendor selection you should:

  • Consider QA vendors with experience in microservices testing or ample experience in test automation.
  • Look through the portfolio for microservices software testing or test automation projects.
  • Consider the testing vendor’s tool and resources stacks to meet your microservices application’s specifics and scale.
  • Short-list 3-5 vendors with relevant hands-on experience and resources.
  • Request microservices testing cost estimate and service-specific presentation from the shortlisted vendors. This way, you can get an understanding of the vendor’s approach to microservices test team lineup, the planned test automation involvement, testing toolkit, and therefore, decide on microservices testing ROI.
  • Decide on the most appropriate microservices testing vendor.
  • Negotiate a SLA and microservices testing costs, sign a collaboration contract.

3. Microservices testing launch

Duration: Up to 2 weeks

To launch the microservices testing process, either an outsourced or an in-house testing team should:

  • Choose and configure the test environment.
  • Start to develop test cases and test scripts.
  • Get down to manual or automated test data generation.

Microservices Testing Sourcing Models

QA management and implementation are in-house

You have complete control over the microservices testing process. At the same time, there are risks bound to incorrect testing efforts estimation, the lack of test automation talents, an unbalanced test automation strategy, the irrelevant selection of testing tools and frameworks.

QA management is in-house; a test team is completely or partially external

You can optimize microservices testing costs by quickly scaling up and down the number of QA talents. Still, you need a well-versed QA manager to design the testing process, manage and regularly assess the microservices testing progress and the external QA team’s performance.

QA management and team are outsourced

You get well-established microservices testing with experienced QA management, test automation excellency, and microservices testing best practices. Still, you should be careful during the vendor selection process and ready to eliminate possible communication issues within microservices teams.

Microservices Testing Costs

Each microservices testing project is as different as each microservices solution. Let’s take as an example a microservices project with the following characteristics:

  • 10-month long.
  • 2-week iterations with testing going in parallel.
  • 100 new test cases per iteration.
  • 80% coverage by automated tests.

The rough estimate for such testing project including senior test engineers’ rates, testing tools’ licenses and test environment costs, will be $50,000.

Microservices testing cost factors include:

For an outsourced option

  • The number of iterations.
  • The number of new test cases per iteration.
  • The percentage of automation test coverage.
  • Test cases/script development and maintenance efforts (complex end-to-end tests require much more build and maintenance time).
  • Test team members’ rates.

For an in-house option

  • The number of microservices and the pace of their deployment.
  • The complexity of each microservice’s functionality.
  • The number of required third-party integrations.
  • Microservices performance requirements.
  • The number of test engineers and test automation engineers.
  • The cost of employed tools (for example, licenses and test servers).
