AWS Testing

Launched in 2006, AWS (Amazon Web Services) has grown into one of the world’s most comprehensive and widely adopted cloud platforms. It offers over 200 fully featured services from data centers globally. These services fall into various categories, including computing, storage, databases, networking, analytics, machine learning, Internet of Things (IoT), security, and enterprise applications, among others.

Integrating AWS products into your business

You might have heard of or even used AWS products like EC2, S3, RDS, DynamoDB, VPC, and SNS. AWS offers an excellent toolkit to help you achieve these product integrations.

  • AWS SDKs and APIs: These tools act as bridges between your custom code and AWS services. You can write code in your preferred language using the SDKs or interact with the service APIs directly using HTTP requests. This code can control how you interact with the service, triggering actions, processing data, and customizing the overall workflow within your system. For instance, you can write custom logic to filter the data retrieved from an Amazon DynamoDB table before using it in your application.
  • AWS Lambda: This serverless compute service allows you to upload and run your custom code without managing servers. You can trigger these Lambda functions from various AWS services or your application. This enables you to inject custom functionality at different points within the AWS service workflows. For example, you could write a Lambda function triggered by file upload events in S3 to perform image resizing or data validation before storing the file.

Note: You cannot alter the core functionalities of AWS products, but you can achieve a high degree of customization by writing code that interacts with them through SDKs, APIs, and services like Lambda.

Selling on AWS Marketplace

The AWS Marketplace is designed to help customers quickly discover a wide range of third-party software and services that they might need for their businesses, all integrated and ready to deploy on AWS.

If you’re someone who’s interested in selling in the AWS Marketplace, you need to register there as a seller. Once you’ve done this, create your application. The programming language you’ll need to develop your AWS Marketplace app depends on the application type you’re building.

Testing AWS product integrations and apps

Once you’ve integrated the product of your choice into your business or created an app for the Marketplace, you need to test it. Testing your code at different levels through unit, integration, and end-to-end testing will be an excellent way to ensure good-quality integrations.

Besides these techniques, you should also consider other non-functional testing techniques to check various aspects of your system, like performance, security, accessibility, and scalability.

Unit testing AWS product integrations and apps

Unit testing is crucial for ensuring the functionality of your code, especially when integrating with AWS products. It is most effective when practiced throughout the development lifecycle, ideally as part of a continuous integration and continuous delivery (CI/CD) pipeline.

Depending on the scripting languages used, like Java, relevant frameworks like JUnit might be employed for unit testing specific code components. Libraries like Mockito for Java allow you to create mock objects that simulate the behavior of AWS services in a controlled environment during unit tests. For instance, you can mock an S3 client to return predefined responses for your S3 interaction logic. Some AWS SDKs offer built-in mechanisms for stubbing responses.

AWS also offers tools and libraries like AWS SDK Test Bench for Java or Moto for Python that can simplify the mocking and testing of AWS interactions within your code.

Integration testing AWS product integrations and apps

While unit tests are valuable, using integration tests to verify how your application interacts with real AWS services in a dedicated test environment is crucial. This can catch issues that unit tests might miss. You can utilize standard testing frameworks like JUnit for Java or Pytest for Python, which are also used for doing unit testing. Besides these, AWS offers some more tools to help you perform integration testing effectively.

  • AWS SDK Test Bench (Java): This tool helps build and run application integration tests using the AWS Java SDK. It allows you to mock AWS service responses and manage test data within your test environment.
  • AWS Step Functions: This service can be used to orchestrate and automate complex workflows involving multiple AWS services. You can integrate Step Functions into your integration tests to simulate real-world interactions between various services.
  • AWS Toolkit for Visual Studio and Eclipse: These IDE plugins offer functionalities like service mocking and test execution for integration testing with AWS services when developing with Java or .NET.
  • AWS SAM Local: This tool allows you to test serverless applications locally built with AWS Serverless Application Model (SAM) templates. It can simulate AWS Lambda functions and other serverless resources during integration testing.

End-to-end testing of AWS product integrations and apps

End-to-end testing is crucial for verifying the overall user experience of your application, including its interactions with AWS products. When focusing from an end user’s perspective, you should opt for testing tools that can handle UI-based testing in an easy way for testers to work with.

While AWS doesn’t offer a single, comprehensive service solely for E2E testing, it provides tools and resources that can be integrated into your E2E testing strategy. You can find some good options of tools in the market for automating end-to-end testing. One such tool that can work wonders for your QA is testRigor.

testRigor for end-to-end testing

When it comes to testing AWS product integrations in your system or apps built for the AWS marketplace, you need a robust testing tool that can seamlessly work with the different platforms and systems under test. This is where testRigor comes into the picture. It is a generative AI-based cloud testing platform that automates and makes all types of end-to-end, functional, regression, UI, and even API test cases accessible to everyone.

Here are some reasons why it works so well for testing AWS integrations or apps.

  • A single tool that tests all: With testRigor, you can test across platforms, browsers, and devices and even test native mobile and native desktop apps. This comes in handy when working with AWS products.
  • Create tests easily: Not just developers but even manual testers and other team members who are not proficient in coding can work with this tool due to its simplistic test case creation using plain English language. You can even use their record-and-playback tool to capture test cases and also leverage their generative AI test case creation feature. Read about testRigor being the automation testing tool for manual testers.
  • Bare minimum test maintenance: testRigor uses AI and self-healing to make your test maintenance woes minimal, allowing you to spend your time and energy on creative test case writing.
  • Easy testing of real-world test scenarios: testRigor’s powerful test library supports testing real-world scenarios like 2-factor authentication, SMS, email content, audio testing, video testing, table interaction, comparing screens, file testing, and more. All of this is possible using plain English statements.
  • Intuitive test reporting: This tool captures every single step of test execution and gives screenshots and video recordings, making it very easy to know what the test execution looked like. You will also find additional developer information and error information appended to each test step, as and when necessary.
  • Easy integrations with existing services: You need not worry about integrating testRigor with other software that you currently have as a part of your QA efforts, as this tool integrates with most of the popular software.
