Principles of Shift Left Testing
Posted: Thu Jan 23, 2025 4:38 am
Shift Left Testing is based on a few basic principles. These include:
Extensive collaboration: Developers, testers, and stakeholders work together from the beginning to ensure quality is considered at every stage.
Early involvement: Testing begins early in the development process so you can identify and address potential issues earlier.
Balanced test automation: Automated tests run frequently, allowing you to gain insights faster and detect problems as soon as they arise.

Benefits of Left Shift Testing
Aside from saving costs and preventing last-minute anxiety, there are several benefits you can derive from incremental shift-left testing. Here are some of them:
Comprehensive risk mitigation
By participating in the early stages of the testing process, teams can detect risks related to new features or code changes before they impact the entire system. This proactive approach ensures that critical application paths are thoroughly tested, reducing the likelihood of failures in the production environment.
Reduced operating costs and last-minute fixes
Detecting problems early helps avoid costly repairs and project setbacks that often arise when errors are canadian cto cio email list found later in the process. This reduces overall development costs and speeds up product time to market .
A chart from Capers Jones, an expert in software development metrics, also supports this claim by showing that the longer bugs are left unfinished, the more expensive they become.

Improving collaboration between development and testing teams
Shift left testing encourages the inclusion of testers from the earliest phases of the project, such as requirements gathering, daily standups, and sprint planning sessions, to ensure that all team members are aligned on project goals and quality standards.
This gives testers a better understanding of the project scope and objectives, allowing them to design tests that meet user expectations and project goals.
Collaboration between testers and developers also allows developers to have a continuous feedback loop that allows them to make adjustments based on immediate results. This reduces the likelihood of major defects occurring later on.in the process.
