From code to commissioning, depending on mission criticality, Engineering and DevOps teams put applications through various tests to ensure enterprise requirements are met. 

Pre-deployment tests include:

Stress Testing

Load Testing

Performance Testing

Chaos Testing

Sanity Testing

Smoke Testing

Post-deployment, DevOps or Development teams may carry out Pre-flight and/or Dry-run Testing as part of a “Shift Left” approach. They move the testing phase earlier in the software development life cycle (SDLC) versus doing testing only at the tail end. This ensures alignment of product specifications to stakeholder requirements and a better-quality product. 

“Shift Left” Testing Benefits

  • Lower costs as bugs detected earlier are cheaper to fix
  • Increased efficiency in the software development process
  • Improved product quality from earlier bug detection
  • Reduced time to market with a shorter QA process
  • Competitive advantage as development teams can build and innovate in iterations

Testing Challenges for Kubernetes-based Applications.

When it comes to testing for Kubernetes-based applications, are there particular considerations? In scaling applications on Kubernetes, teams will grapple with the speed at which Kubernetes evolves, cluster scalability, networking & storage, observability & monitoring and potentially a host of security and compliance issues.

Consider the following for Kubernetes application testing:

Configuration

Once the tools have been chosen, there will be the usual learning curve and time required to set up and configure the tools correctly.

How complicated an effort this will be depends on the specific test suite.

Access Restrictions

Access control can limit what can be accessed or executed within a cluster.

What network access and security restrictions are applicable for your Kubernetes deployments?

Is your Kubernetes deployment following the access control as per compliance?

GitOps

GitOps is an operational framework that takes DevOps best practices used for application development and applies them to infrastructure automation.

If you are managing all cluster states with Git, how do you tie in your testing and test-related artifacts?

Application Coupling

What happens when you need to run tests that are not in sync with your build?

For example, you have updated a component and just want to rerun specific parts of your test suite, how do you execute this?

Measuring and Monitoring

Monitoring systems are the core component of any system.

Do you already have measuring and monitoring in place?

How will you measure and benchmark your testing efforts?

Test Tool Diversification & Vendor Lock-in

There is a huge list of tools to consider.

What is your team’s approach when it comes to tools?

Is vendor lock-in a concern?

Kubernetes Application Testing with CAEPE.

CAEPE™ is not a testing platform. CAEPE enables teams to make pre/post deployment testing and QA an integral part of the enterprise application deployment process.

CAEPE’s Confident Delivery Features

Confident Delivery is how CAEPE defines best practices for your applications to be delivered well.

One-click access

CAEPE’s Confident Delivery features provide users with one-click access to key pre-deployment and post-deployment tests such as Smoke Testing, Sanity Testing, Load Testing, Stress Testing, Chaos Testing, Pre-flight Testing and Dry-Run Testing.

Smooth integration

With CAEPE’s Confident Delivery features, DevOps teams can integrate existing testing tools and mandate specific tests within deployment workflows. Development and QA teams can be empowered to deploy applications. Learn more about CAEPE’s features.

Easy onboarding

For Development teams typically not exposed to testing, CAEPE provides an easy on-boarding experience to use testing features. They can run and execute the various tests quickly and independently.

This facilitates a “Shift Left” approach and preliminary testing to ensure what is being developed is aligned to stakeholder requirements.

Reduces complexity

CAEPE’s support for multi-cloud and hybrid deployments further reduces the complexity of testing across multiple environments.

For example, if you have a stateful multi-cloud application across AWS, Azure and GCP, CAEPE’s one-click deployment reduces the time required to separately deploy to each environment.

Industry standards

In addition, CAEPE adheres and enforces industry best practices for operations and configurations and provides for standard progressive delivery strategies – further reducing the likelihood of manual errors or human inconsistencies. 

Testing Supported through CAEPE’s Confident Delivery Features

Stress Testing

Verify application stability & reliability

Measure application robustness and error handling under extremely heavy loads and ensuring applications don’t crash under crunch situations.

Commonly used tools: Jmeter, Load Runner

Load Testing

Test application performance under specific loads

Improve performance bottlenecks and ensure application stability pre-deployment.

Commonly used tools: Jmeter, Load Runner

Performance Testing

Test application performance under specific loads

Improve performance bottlenecks and ensure application stability pre-deployment.

Commonly used tools: Jmeter, Load Runner, Blaze Meter

Chaos Testing

Test system’s integrity before they lead to unplanned downtime or a negative user experience

Simulate and identify failures in a given environment. A system of monitoring tools is set up and chaos testing run in a production environment. This approach allows teams to do a real-life simulation of how their application or service responds to different pressures and stresses.

Commonly used tools: Gremlin, Steadybit

Sanity Testing

Rapidly evaluate whether the basic functionality of a new software build is working correctly or not

Check that critical functionality is working.

Commonly used tools: Scripting

Smoke Testing

Determine whether the deployed software build is stable or not. QA teams use smoke testing to confirm if they can proceed with further software testing.

Commonly used tools: Scripting

Dry-run Testing

Reduce negative effectives of product failure. Typically run by developers as a static test.

Commonly used tools: Scripting

Pre-flight Testing

Validate an environment or application before installation to prevent common errors

Commonly used tools: Manual troubleshooting
