SDLC’s Design Phase:
The next phase in the SDLC is “Design”- this is where the functional requirements are translated into the technical details. The dev, design, environment and data teams are involved in this step. The outcome of this step is typically a Technical Design Document- TDD. The input is the SRS document both for the creation of the TDD and for the QA team to start working on the QA aspect of the project- which is to review the SRS and identify the test objective.
What is an SRS review?
SRS is a document that is created by the development team in collaboration with business analysts and environment/data teams. Typically, this document once finalized will be shared with the QA team via a meeting where a detailed walk through is arranged. Sometimes, for an already existing application, we might not need a formal meeting and someone guiding us through this document. We might have the necessary information to do this by ourselves.
SRS review is nothing but going through the functional requirements specification document and trying to understand what the target application is going to be like.
The formal format and a sample were shared with you all in the previous article. It does not necessarily mean that all SRSs are going to be documented that way exactly. Always, form is secondary to the content. Some teams will just choose to write a billeted list, some teams will include use cases, some teams will include sample screenshots (like the document we had) and some just describe the details in paragraphs.
Pre-steps to software requirements specification review:
Step #1: Documents go through multiple revisions, so make sure we have the right version of the reference document, the SRS.
Step #2: Establish guidelines on what is expected at the end of the review from each team member. In other words, decide on what deliverables are expected from this step – typically, the output of this step is to identify the test scenarios. Test scenarios are nothing but one line pointers of ‘what to test’ for a certain functionality.
Step #3: Also establish guidelines on how this deliverable is to be presented- I mean, the template.
Step #4: Decide on whether each member of the team is going to work on the entire document or divide it among themselves. It is highly recommended that everyone reads everything because that will prevent knowledge concentration with certain team members. But in case of a huge project, with the SRS documents running close to 1000 pages, the approach of breaking up the document module wise and assigning to individual team members is most practical.
Step #5: SRS review also helps in better understanding if there are any specific prerequisites required for the testing of the software.
Step #6: As a byproduct, a list of queries where some functionality is difficult to understand or if more information needs to be incorporated into functional requirements or if mistakes are made in SRS they are identified.
What do we need to get started?
The correct version of the SRS document
Clear instructions on who is going to work on what and how much time have they got.
A template to create test scenarios
Other information on- who to contact in case of a question or who to report in case of a documentation inconsistency
Who would provide this information?
Team leads are generally responsible for providing all the items listed in the section above. However, team members’ inputs are always important for the success of this entire endeavor.
Team leads often ask- What kind of inputs? Wouldn’t it be better to assign a certain module to someone interested in it than to a team member who is not? Wouldn’t it be nice to decide on the target date based on the team’s opinion than thrust a decision on them? Also, for the success of a project, templates are important. As a general rule, templates have a higher rate of efficiency when they are tailored to the specific team’s convenience and comfort.
It should therefore be noted that, team leads more than anything are team members. Getting your team onboard on the day-to-day decisions is crucial for the smooth running of the project.
Why a template for test scenarios – isn’t it enough if we just make a list?
It sure is. However, software projects are not ‘one-man’ shows. They involve team work. Imagine in a team of 4- if each one of them decide to review one module of the software requirements specification each. Team member A has made a list on a sheet of paper. Team member 2 used an excel sheet. Team member 3 used a notepad. Team member 4 used a word doc. How do we consolidate all the work done for the project at the end of the day?
Also, how can we decide which one is the standard and how can we say what is right and what’s not if we did not create the rules to begin with?
That is what template is- A set of guidelines and an agreed format for uniformity and concurrence for the entire team.
The table below will let us create the test scenarios. The columns included are:
Column #1: Test scenario ID
Every entity in our testing process has to be uniquely identifiable. So, every test scenario has to be assigned an ID. The rules to follow while assigning this ID have to be defined. For the sake of this article we are going to follow the naming convention as: TS(prefix that stands for Test Scenario) followed by ‘_’ , module name MI(my Info module of the Orange HRM project) followed by ‘_’ and then the sub section (eg: MIM for My info module, P for photograph and so on)followed by a serial number. An example would be: “TS_MI_MIM_01”.
Column #2: Requirement
It helps that when we create a test scenario we should be able to map it back to the section of the SRS document where we picked it from. If the requirements have IDs we could use that. If not section numbers or even page numbers of the SRS document from where we identified a testable requirement will do.
Column #3: Test scenario description
A one liner specifying ‘what to test’. We would also refer to it as test objective.
Column #4: Importance
This is to give an idea about how important certain functionality is for the AUT. Values like high, medium and low can be assigned to this field. You could also choose a point system, like 1-5, 5 being most important, 1 being less important. Whatever the value this field can take, it has to be pre-decided.
Column #5: No. of Test cases
A rough estimate on how many individual test cases we might end up writing that one test scenario. For example: To test the login- we include these situations: Correct username and password. Correct username and wrong password. Correct password and wrong username. So, validating the login functionality will result in 3 test cases.
Note: You can expand this template or remove the fields as you see fit.
