Testing as a Service

Testing as a Service

It is important to assess and implement the right methodologies to achieve scale, minimize costs and offer improved services. Testing-as-a-Service (TaaS) is considered a viable testing model by many organizations to achieve reduced costs and improved service for their IT test requirements.

TaaS can be used for various QA activities, such as:

  • Functional Testing
  • Load / Stress Testing
  • Performance and Benchmark Testing
  • Regression Testing

Advantages of TaaS over traditional testing

  • Scalable model via public cloud – utilize computing power, disk space, memory as per current requirements but have the ability to ramp up on demand very quickly
  • Costs – Pay for what you use. No need to own your own infrastructure. No capital costs incurred.
  • Licensing benefits – Operating system (OS), test tools, hardware, application licenses are managed by the cloud.
  • Standardization – Centralized test environment with a standard set of tools and processes will ensure repeatability, efficiency and quality results

Types of TaaS

Functional Testing as a Service:
TaaS Functional Testing may include UI/GUI Testing, regression, integration and automated User Acceptance Testing (UAT) but not necessary to be part of functional testing.

Performance Testing as a Service:
Multiple users are accessing the application at the same time. TaaS mimic as a real-world users environment by creating virtual users and performing the load and stress test.

Security Testing as a Service:
TaaS scans the applications and websites for any vulnerability.

Benefits of Cloud Testing

  • Flexible Test Execution and Test Assets
  • Some users claim 40-60% savings in the cloud testing vs. the traditional testing model
  • Achieve a fast return of investments by eliminating the investment made after hardware procurement, management, and maintenance, software licensing, etc.
  • Deliver product in quicker time through rapid procurement, project set-up, and execution
  • Ensure data integrity and anytime anywhere accessibility
  • Reduce operational costs, maintenance costs and investments
  • Pay as you use

Different Levels of Maturity Model

The five levels of the TMM helps the organization to determine the maturity of its process and to identify the next improvement steps that are essential to achieving a higher level of test maturity.

TMM Levels Goals An objective of TMM levels
Level 1: Initial Software should run successfully
  • At this level, no process areas are identified
  • An objective of testing is to ensure that software is working fine
  • This level lacks resources, tools, and trained staff
  • No Quality Assurance checks before software
Level 2: Defined Develop testing and debugging goals and policies
  • This level distinguish testing from debugging & they are considered distinct activities
  • Testing phase comes after coding
  • A primary goal of testing is to show software meets specification
  • Basic testing methods and techniques are in place
Level 3: Integrated Integration of testing into the software lifecycle
  • Testing gets integrated into an entire life cycle
  • Based on requirements test objectives are defined
  • Test organization exists
  • Testing recognized as a professional activity
Level 4: Management and Measurement Establish a test measurement program
  • Testing is a measured and quantified process
  • Review at all development phases are recognized as tests
  • For reuse and Regression Testing, test cases are gathered and recorded in a test database
  • Defects are logged and given severity levels
Level 5: Optimized Test process optimization
  • Testing is managed and defined
  • Testing effectiveness and costs can be monitored
  • Testing can be fine-tuned and continuously improved
  • Quality control and Defect prevention are practiced
  • Process reuse is practiced
  • Test related metrics also have tool support
  • Tools provide support for Test Case design and defect collection

Difference between CMM & TMM

CMM or Capability Maturity Model is for judging the maturity of the software TMM or Test Maturity Model describes the process of testing and is related to monitoring
