BCS Level 4 Software Development Methodologies

What is the role of a developer

• Generally involved in design, testing and maintenance of software programs. They are involved in the technical documentation of the software they have produced, annotating code.

• Taking feedback from beta testers and fixing bugs they have found and dealing with bug reports post-release.

• looking at both processes and at the finished product to ensure that the processes support high quality product production and to see whether this has actually happened.

• Decides on roles within a team

Which is black box testing

• where you have access to the code and use it to dry run or desk check the code to see if there is a problem.

• Checking code syntax

• manually working through their code to trace the value of variables

• you don't look at the code, but simply pass test data to a function which has a given purpose and see if the correct results are produced

What is white box testing

• Unit testing is a software testing method by which individual units of source code are tested to determine whether they are fit for use.

• manually working through their code to trace the value of variables

• where you have access to the code and use it to dry run or desk check the code to see if there is a problem.

• you don't look at the code, but simply pass test data to a function which has a given purpose and see if the correct results are produced

What is a Tech architect

• Creating detailed, comprehensive and well-structured test plans and test cases.

• Understand company needs to define system specifications

• Reviewing quality specifications and technical design documents to provide timely and meaningful feedback.

• Monitor systems to ensure they meet both user needs and business goals

What is the role of a Quality Assurer

• Deals with the items that need to be specifically designed and implemented in code vs those things that relate to the environment

• Looking at both processes and at the finished product to ensure that the processes support high quality product production

• Removing ambiguity, assumptions, wishful thinking, grey areas and interpretations from a project’s requirements.

• Estimating, prioritising, planning and coordinating quality testing activities.

The most important input into the 'analysis stage’ is

• Development Tools

• cost-benefit results.

• customer requirements

• required project roles

What is the main purpose of using ‘High Level’ design in application development?

• To identify all issues associated with the system

• To determine the communication processes between entities.

• To determine the enhanced user experience.

• To ensure the requirements are achievable.

Which one of the following is viewed as a ‘benefit’ when using prototyping as a development method?

• The pace of development is fast.

• A formal test strategy is implemented.

• The pace of development is fast

• All non-functional requirements are implemented.

An important consideration when choosing a suitable programming language can be the

• clients’ non-functional requirements

• testing of functional requirements.

• end users’ preference

• developers' preference

What is the purpose of ‘functional testing’?

• Establish that the application runs on a specific operating system.

• Confirm the speed of system response.

• Establish that the application runs on a specific operating system

• Confirm the ability to perform intended tasks.
