Testing Microservices Applications

The shift towards microservices and modular applications makes testing more important and more challenging at the same time. You have to make sure that the microservices running in containers perform well and as intended, but you can no longer rely on conventional testing strategies to get the job done.

This is where new testing approaches are needed. Testing your microservices applications require the right approach, a suitable set of tools, and immense attention to details. This article will guide you through the process of testing your microservices and talk about the challenges you will have to overcome along the way. Let’s get started, shall we?

A Brave New World

Traditionally, testing a monolith application meant configuring a test environment and setting up all of the application components in a way that matched the production environment. It took time to set up the testing environment, and there were a lot of complexities around the process.

Testing also requires the application to run in full. It is not possible to test monolith apps on a per-component basis, mainly because there is usually a base code that ties everything together, and the app is designed to run as a complete app to work properly.

Microservices running in containers offer one particular advantage: universal compatibility. You don’t have to match the testing environment with the deployment architecture exactly, and you can get away with testing individual components rather than the full app in some situations.

Of course, you will have to embrace the new cloud-native approach across the pipeline. Rather than creating critical dependencies between microservices, you need to treat each one as a semi-independent module.

The only monolith or centralized portion of the application is the database, but this too is an easy challenge to overcome. As long as you have a persistent database running on your test environment, you can perform tests at any time.

Keep in mind that there are additional things to focus on when testing microservices.

  • Microservices rely on network communications to talk to each other, so network reliability and requirements must be part of the testing.
  • Automation and infrastructure elements are now added as codes, and you have to make sure that they also run properly when microservices are pushed through the pipeline
  • While containerization is universal, you still have to pay attention to specific dependencies and create a testing strategy that allows for those dependencies to be included

Test containers are the method of choice for many developers. Unlike monolith apps, which lets you use stubs and mocks for testing, microservices need to be tested in test containers. Many CI/CD pipelines actually integrate production microservices as part of the testing process.

Contract Testing as an Approach

As mentioned before, there are many ways to test microservices effectively, but the one approach that developers now use reliably is contract testing. Loosely coupled microservices can be tested in an effective and efficient way using contract testing, mainly because this testing approach focuses on contracts; in other words, it focuses on how components or microservices communicate with each other.

Syntax and semantics construct how components communicate with each other. By defining syntax and semantics in a standardized way and testing microservices based on their ability to generate the right message formats and meet behavioral expectations, you can rest assured knowing that the microservices will behave as intended when deployed.

Ways to Test Microservices

It is easy to fall into the trap of making testing microservices complicated, but there are ways to avoid this problem. Testing microservices doesn’t have to be complicated at all when you have the right strategy in place.

There are several ways to test microservices too, including:

  • Unit testing: Which allows developers to test microservices in a granular way. It doesn’t limit testing to individual microservices, but rather allows developers to take a more granular approach such as testing individual features or runtimes.
  • Integration testing: Which handles the testing of microservices in an interactive way. Microservices still need to work with each other when they are deployed, and integration testing is a key process in making sure that they do.
  • End-to-end testing: Which⁠—as the name suggests⁠—tests microservices as a complete app. This type of testing enables the testing of features, UI, communications, and other components that construct the app.

What’s important to note is the fact that these testing approaches allow for asynchronous testing. After all, asynchronous development is what makes developing microservices very appealing in the first place. By allowing for asynchronous testing, you can also make sure that components or microservices can be updated independently to one another.

Quality Assurance Services | Best QA team for Hire

Software testing is often underrated when it comes to tight deadlines and deliverables. Developers try to compromise in software testing phases, and this leads to more confusion and client dissatisfaction. A professional software developer is the one who remains calm an ensures that the developed solutions go through proper checks and trouble shooting well before the software is due to be delivered or deployed. There are situations when the software development companies do not have an in-house testing team or lack certain tools and resources. In this case, they use third party software testing companies to complete the process.

Software Testing-All you need to know about

Software testing, we all know is a mandatory process that needs to be carried out during, after and beyond the development of any software solution. It helps identify major and minor glitches. Early and regular identification, can help programmers ensure that the finished product is error free. Imagine, developing a software and deploying it without any testing or quality checks? What would be the result? The answers could be endless and rolling out a software this way could jeopardize an entire software development organization.

The lack of proper and robust software testing is a major problem facing development companies. This can be due to many reasons. So when integrating a successful testing processes into software development, a development company should keep a few things in mind.

What software testing actually means

Verifying whether software meets the expected parameters. It is not a superficial but an in-depth process
A healthy process involves investigating the product to find any information that is of value to the stakeholders.
Trying to identify problems before software is released to stakeholders
An integral step in software development that is often underrated is constant communication with stakeholders and collaboration to improve the product
It is important to keep these points in mind when searching for a good software testing partner. Getting software testing done by a third-party vendor is not an easy task because it can be hard to determine if a company will be a good partner or a bad one. Your knowledge of proper testing and quality assurance processes comes into play here.

How to excel in manual quality testing

Proper Organization
Organization is an important step not only in testing but other processes too. When we talk about manual testing, it becomes necessary to create an organized structure to store all the relevant details of the project so that no integral information is lost or missed. The stored information and communication details are helpful when creating a successful testing strategy and revisiting information exchanged earlier.

Writing detailed bug reports
Bug reports submitted by the tester are of the utmost importance because these reports contain reports of genuine issue in the application. A detailed report is a great benefit to developers because they can just go through it and see what needs to be done next. If the bug report is not clear or it is incomplete, it creates confusion and may lead to misunderstandings or delayed delivery dates.

Clarity in test cases
The optimal size for a test case is 3 to 8 steps. Clarity in test cases can determine the efficiency in your testing tasks. Just like a detailed bug report is important similarly clear and precise test cases are required to carry out and effective testing process. Test cases should not be very long, the longer the test case the trickier it will be for the developer to work through it.

Besides clear case studies and complete bug reports, the tester must have ability to be focused and stay positive while testing the software application. These features enhance the testing process and make it more reliable.

Software Testing 101: Regression Tests, Unit Tests, Integration Tests

Automation and segregation can help you build better software
If you write automated tests and deliver them to the customer, he can make sure the software is working properly. And, at the end of the day, he paid for it.

Ok. We can segregate or separate the tests according to some criteria. For example, “white box” tests are used to measure the internal quality of the software, in addition to the expected results. They are very useful to know the percentage of lines of code executed, the cyclomatic complexity and several other software metrics. Unit tests are white box tests.

How to Do API Testing?

Nowadays API testing is an integral part of testing. There are a lot of tools like postman, insomnia, etc. There are many articles that ask what is API, What is API testing, but the problem is How to do API testing? What I need to validate.

Note: In this article, I am going to use postman assertions for all the examples since it is the most popular tool. But this article is not intended only for the postman tool.

Let’s directly jump to the topic.

Let’s consider you have an API endpoint example http://dzone.com/getuserDetails/{{username}} when you send the get request to that URL it returns the JSON response.

My API endpoint is http://dzone.com/getuserDetails/{{username}}

The response is in JSON format like below

JSON

{
  "jobTitle": "string",
  "userid": "string",
  "phoneNumber": "string",
  "password": "string",
  "email": "user@example.com",
  "firstName": "string",
  "lastName": "string",
  "userName": "string",
  "country": "string",
  "region": "string",
  "city": "string",
  "department": "string",
  "userType": 0
}

In the JSON we can see there are properties and associated values.

Now, For example, if we need details of the user with the username ‘ganeshhegde’ we need to send a **GET **request to **http://dzone.com/getuserDetails/ganeshhegde **

dzone.com

Now there are two scenarios.

1. Valid Usecase: User is available in the database and it returns user details with status code 200

2. Invalid Usecase: User is Unavailable/Invalid user in this case it returns status with code 404 with not found message.

Top 10 Automation Testing Tools: 2020 Edition

The demand for delivering quality software faster — or “Quality at Speed” — requires organizations to search for solutions in Agile, continuous integration (CI), and DevOps methodologies. Test automation is an essential part of these aspects. The latest World Quality Report 2018–2019 suggests that test automation is the biggest bottleneck to deliver “Quality at Speed,” as it is an enabler of successful Agile and DevOps adoption.

Test automation cannot be realized without good tools; as they determine how automation is performed and whether the benefits of automation can be delivered. Test automation tools is a crucial component in the DevOps toolchain. The current test automation trends have increased in applying artificial intelligence and machine learning (AI/ML) to offer advanced capabilities for test optimization, intelligent test generation, execution, and reporting. It will be worthwhile to understand which tools are best poised to take advantage of these trends.****
