How to Apply Shift-Left Testing in Continuous Testing?

    In today’s fast-paced market, the demand to deliver quality software products in a cost and time-effective manner continues to accelerate. When you get the software to market faster, you gain a competitive advantage. Shift-left testing and continuous testing is a great combination to accommodate that need. To help you better understand these two notions, in this article, we will walk you through the definition of each method, their benefits and how to implement them into your SDLC.

    What is Continuous Testing?

    Continuous Testing is a software testing type in which the product is evaluated early, often, and throughout the entire continuous delivery process. In short, continuous testing is all about testing early and often. 

    You may ask why continuous testing is so valuable, the answer is saving time. Incorporating continuous testing into your organization’s testing strategy accelerates your time-to-market but keeps the quality your customers expect. Moreover, this testing type also enables constant feedback for developers to fix bugs before being released to production, and as such, make the process run much faster.

    What is Shift-Left Testing?

    Shift-left testing is an approach of bringing testing earlier into the developer lifecycle while improving quality measures. Unlike the traditional testing method where testing is brought in at the end of the development process, the idea of shift-left testing is to involve testing from the beginning of the design phase to build an appropriate testing strategy. Finding problems as soon as possible reduces the amount of time spent resolving them and reduces the change of testing becoming a bottleneck to a fast release. 

    Additionally, with shift-left testing practices in place, the product team is now incorporate testing early in their pipeline, thus advance faster, seamlessly improve and win over the competition in the market.

    Why Shift-Left Testing Matters in Continuous Testing?

    While shift-left testing has a myriad of key benefits, the technique alone is not enough. Shift-left testing should be incorporated into continuous testing so that testers can generate more frequent, holistic and more practical tests with the implementation of real functional data. The combination “shift-left continuous testing” adds to the automation of your application testing, ensures that it is utilized as much, as early, and as continuous as possible throughout the product development pipeline.

    In other words, by incorporating shift-left testing and continuous testing, bug detection can be done more efficiently in the early stage, resulting in higher quality feedback and faster issue resolution with lesser effort.

    How to Apply Shift-left Testing in Continuous Testing?

    As shift-left and continuous testing employ the same process of testing at every stage and as often as possible, it’s safe to say that shift-left testing is a part of continuous testing. While shift-left testing focuses on defined objectives, continuous testing is part of the process of executing tests in the DevOps pipeline to get feedback on bugs as soon as possible. Therefore, if continuous testing incorporates the entirety of the DevOps pipeline (i.e. from planning, designing, developing to deploying), shift-left takes a part of each cycle and sets testing strategies for each task in the cycle. Shift-left testing enhances continuous testing and makes it a stronger weapon against bugs. 

    Additionally, you can apply shift-left testing through BBD (behaviour-driven development). BDD, for those who don’t already know, is a versatile Agile software development approach that enhances collaboration between developers and non-technical team members (e.g. managers). 

    Katalon Studio is a powerful tool for you to implement BDD into shift-left testing through Jira integration.


    More and more, companies are finding out that the old style is simply not conducive to rapid releases. After all, time is money. Shifting testing practices left and incorporate testing as early as possible allows software businesses to beat their competition to the market.

    The Essential Guide To End-to-End Testing | E2E Testing 101

    End-to-end testing is one of the most effective ways to ensure the quality of the product you will be shipping. However, it’s not an easy task to make a jump to this methodology. If the thought of end-to-end testing makes you sweat, this article will help you shape up.


    What is End-to-end Testing?

    End-to-end (E2E) testing is defined as a technique that tests the entire software product from beginning to end to ensure the application flow behaves as expected. The goal of this testing type is to test from the end user’s experience. It also helps define the product’s system dependencies and ensure all integrated pieces work together as expected.

    Why E2E testing matters

    E2E testing matters to many groups within an organization, such as managers, testers and developers. 

    • Managers: Managers like this testing procedure as it lets them know how a failing test would impact the user. 
    • Testers: Testers find E2E testing useful as it helps them verify real-world behavior, and as such, they can avoid problems and achieve a greater sense of accomplishment.
    • Developers: Developers benefit from it because most of the testing is offloaded to others.

    Benefits of E2E Testing

    The adoption of E2E testing yields the following advantages:

    • Expand test coverage
    • Ensure the correctness of the application
    • Reduce time to market
    • Reduce cost
    • Detect bugs

    E2E Testing Life Cycle


    An end-to-end testing life cycle consists of the following main components:

    • Test planning: Specifies key tasks, associated schedule, and resources
    • Test design: Test specifications, test case generation, risk analysis, usage analysis, and scheduling tests
    • Test execution: Executes test cases and documents testing results
    • Results analysis: Analyzes test results, evaluate testing, and perform additional testing if necessary

    When to Apply E2E Testing?

    E2E testing is regularly conducted on finished products and systems, making each review a test of the completed system. A second test will take place if the system does not output what is expected or if a problem is found. In this case, the team will have to record and analyze the data to determine the issue’s origin; then fix and re-test them.

    E2E Testing Methods

    Vertical E2E Testing

    This method refers to testing in layers, meaning that tests happen in sequential, hierarchical order. To ensure quality, each component of a system or product is tested from start to finish. Vertical testing is often used to test critical components of a complex computing system which does not typically involve users or interfaces.

    Horizontal E2E Testing

    A commonly used method occurring horizontally across the context of multiple applications and easily takes place in a single ERP (Enterprise Resource Planning) application. Here’s an example. A Web-based application of an e-commerce system includes accounts, product inventory status, and shipping details.

    Metrics For E2E Testing

    Some of the many metrics used for E2E testing are:

    • Test Case Preparation Status: Used to determine the specific position of the test cases that are under preparation, compared to planned test cases.
    • Test Progress Tracking: Test progress should be tracked on a weekly basis. This step will provide regular details of test completion percentage, such as passed/failed, executed/unexecuted, valid/invalid test cases, and so on.
    • Defects Status and Details: It gives a weekly percentage of open and closed defects. Also, weekly defect distributions are based on severity and priority.
    • Environment Availability: The actual number of operational hours and hours scheduled per day for testing.

    Automate End-to-End Testing in Katalon Studio

    Katalon Studio is an excellent automation tool that can make your end-to-end tests less complicated. There are three core features in Katalon Studio that you can use to apply E2E testing: recorder, built-in keywords, and custom keywords.


    Nowadays, software systems are complex and interconnected with numerous subsystems. If any of the subsystems fails, the whole software system could crash. And this is a major risk and can be avoided by E2E testing. This explains, in part, why E2E testing are currently widely adopted in the industry. So now it’s a good time for you to start learning E2E testing if you haven’t done so, it will be a valuable skillset with high demand for the future to come.
