What is continuous testing?  

Continuous testing (CT) is an approach to software development, where applications are tested continuously throughout their entire life cycle. The goal of CT is to evaluate the software’s quality across the life cycle, providing important feedback earlier and permitting higher-quality and faster deliveries.  

In the past, testing and development teams had been working in silos resulting in tests being extremely time exhaustive. Extensive testing required great number of human hours and with a huge spike in delivery speed and consumer expectations, the traditional system was causing huge bottle necks. It brings the development testing and operations teams together enhancing synergy among the teams and knowledge of individuals.  

While Q/A focuses on standardization and adherence to it, testing involves finding and ironing out the bugs. It also helps in the QA team improve their understanding of the deployment environment. This enhances the quality of their replication of the environment.  

What are the key factors in continuous testing?  

• Minimizing the waiting time by simplification of processes. 

 • The replica of the deployment environment must be as accurate as possible so that the development teams can get all the important feedbacks.  

• It requires different tools with varied capabilities. Hence access to these tools is crucial for continuous testing.  

How is continuous testing carried out?  

It is carried out through the following steps  

1. Generating test automation suite for the requirements.  

2. Setting up a test environment.  

3. Creating test data bed from production data.  

4. Testing API.  

5. Performance testing.  

What are the advantages : 

1. Increase in delivery speed.  

2. Increase in quality.  

3. Increase in synergy between development operations and testing teams.  

4. Better user experience due to faster feature releases. 

5. Reduce risk as the code is checked at multiple stages.  

6. Time saving as testing happens continuously and the waiting time for developers is drastically reduced.  

What is the role of continuous testing in DevOps? 

Initially, it was used to reduce the time taken to collect feedback from testing. Tests are conducted each time the code is modified. Each code branch is separately tested, and the integrated code base is tested for the proper functioning of all the branches put together.  

It is an essential part of DevOps, identifying and resolving issues as early as possible, thus saving cost and time for resolution.
