Agile software development is increasing in popularity and has become widespread amongst tech firms. Agile development methods aim to minimize or eliminate the problems encountered with the classic waterfall model. The key elements are
- Iterative development process in short sprints -customer benefits can be seen earlier on in the process
- Creating the feature list, launched during the go-live phase dynamic – in support of fixed release dates
- Strict risk-based approach to all stages of development, thereby improving the risk control of the project
- Integrating testing early on – building test cases is already part of
the specification stage; test cases contribute to the specification
The strict value/risk based approach and the reduced time to market enable companies to differentiate themselves and to succeed in their industries. As the development of agile projects continue to increase in number, companies will need to adopt a fundamentally different approach to deliver and integrate complex enterprise software applications. ‘Agile’ will evolve into ‘Enterprise-class Agile’ development. Tosca Testsuite enables Agile teams to fully adopt Test Driven Development, or Behavior Driven Development with seamless integration of manual and automated test cases in plain English.
Testing in Agile Software Development
One of the key advantages of agile development, in comparison to the waterfall model is the shorter time-to-market. However, this advantage can only be achieved if testing is significantly involved in development right from the beginning of the project. Short time-to-market is only possible with high quality testing, which equals high test coverage in a short run-time. This leads directly to:
- Optimized effectiveness of test cases, minimum number of test cases with maximum test coverage
- Automated test execution, whenever possible to minimize run-time
- Minimized maintenance effort for existing automated test cases
In the agile method, topic-based teams are formed that cover design, specification, development and testing. Testing is integrated into the design activities right from the beginning. This facilitates the transfer of domain knowledge to the testers, who then define the test cases. Methodical TestCase-Design ensures the effectiveness of testing. Tricentis recommends using the methodical concepts that underlie the Linear Q approach to testing.
Test Early, Test Often – With 3rd Generation Test Automation
TOSCA Automate is third-generation technology that uses a model-based approach. It is unlike any first and second generation technology such as record/replay tools, or tools that require test automation frameworks, such as script-based technologies.
The TOSCA model is derived from the software build itself, in particular its interfaces, and presents an abstract interface catalogue: system model. Making it possible to write test cases that are independent of the underlying software technology and maintained in a “business” language that humans are able to understand
This approach enables agile teams to create tests early, even before systems exist. The created test cases can be used as either manual tests or fully automated tests for systems with graphical user interface as well as non-UI based systems such as web services. The model based approach also helps to maintain test automation throughout the changes that occur during the sprint cycles, which is key to achieve high automation rates.
Many of today’s business applications and process are built upon interconnected systems that communicate information from a large array of client as well as server platforms. Although messaging technologies, business process management and integrations are essential to the on-going interconnectivity of these application and processes, there is still an added risk during the application delivery.
With growing pressures to shorten time-to-market as well as the new and increasing demands for mobile applications and dependency on third party systems, Tosca’s Service Virtualization and Orchestration is ideal for independent creation of software tests from the available sub-systems.
Whether you have time constraints or just need to get your product on the market as quick as possible, Tosca’s service virtualization tool allows you to quickly create intelligent test stubs which enable the development and testing team to perform critical tasks during the early phases of the development cycle.
