How is automation typically applied in a Waterfall lifecycle model?
(Which of the following aspects of “design for testability” is MOST directly associated with the need to define precisely which interfaces are available in the SUT for test automation at different test levels?)
Your company is about to start a project to replace an old sales and merchandising system with a new version that will be based on modern platforms. The main requirements for the system are:
1. Loading sales data, sent electronically from the stores each evening, into a central database.
2. Producing sales reports for the merchandisers, whose job is to manage stock levels in stores.
3. Producing forecast reports, used to predict future demand for each product, based on a combination of sales history and forecasting parameters. The parameters will be entered by the merchandisers into a browser-based front end and the reports will be produced overnight. The users will be able to retrieve the reports, on screen or in print, via an interactive feature.
Requirements 1 and 2 were already met by the old system and will be rewritten in the new system with some minor functional changes. The sales data will, as before, be loaded in an overnight batch run. There have been problems with the old system at peak periods when this run has taken longer than scheduled, so that dependent jobs could not finish before the start of the next working day. The Data Centre manager requires that the new system’s overnight batch runs take 10% less time than the old one, including the new reports, to allow time for all jobs to complete.
Requirement 3 is new. The functionality provided by the UI will be simple and the Sales & Merchandising manager requires that it be easy to use.
The data for testing the reports will be extracted from the old system in production and will be anonymized before use.
The system will be developed using an Agile lifecycle with iterations of fixed length. This will be the first full deployment of this methodology, which has just completed a successful pilot. It is a relatively simple development and is expected to be completed in three releases, each taking approximately 2 months.
You are an experienced TAE and have been recruited to implement test automation on this project and have started to evaluate candidate tools to automate functional and some non-functional testing. It is already clear that no single tool will meet all requirements, and that the developers’ existing Integrated Development Environment will meet the automation needs of their testing. The TAS will need to support CI/CD.
When reviewing your tool comparison table, what two tool capabilities will be MOST beneficial for this project?
i) The ability to support multiple and configurable test environments.
ii) The ability to manage test data in a way that supports version control of the data sets.
iii) The ability to be compatible with other tools that are likely to be used on the project.
iv) The ability to expand the overall test architecture and to be scalable and modifiable.
v) The ability for non-technical users to enter requests for customizable reports.
You are working as a TAE for a small start-up insurance broker and your next project will be a new system for generating motor insurance quotes. The project will follow an Agile methodology. The stakeholders are keen to get it into production, but are realistic about the need to allow enough time for thorough testing and support automation of tests where appropriate.
Which approach for automating the tests would be MOST suitable for this project?
