  • A Better Way – Case Study 3 – Test Plan in a Hurry!

    A Better Way – Case Study 3 – Test Plan in a Hurry!

    In our last several blogs we have discussed ‘A Better Way to Test”.

    The issue is to apply this to actual situations. We have 5 Case Studies we plan to use over the next several weeks to address this. The third case study might be called “Test Plan in a Hurry!”.

    This issue came up from an organisation that was part way through (as usual!) an engagement and suddenly required a test plan to satisfy the client. The request came from the Project Manager on Friday with a deadline of Monday afternoon. There was no prior exposure to the project; no knowledge that the request was coming; and very little in the way of Project Documentation (with certainly no time to review it). There was a temptation to ignore the request and had they not been an existing client, we might have been tempted to point out that this was not really an effective use of time. However, given the nature of the request and the people from whom it came, we went ahead with the attempt.

    Clearly, we were not going to get detailed testcases or test objectives based on what we had been given. So we opted for a process based Master Test Plan. In other words, we put together a statement of how the project would be tackled from a Quality Assurance point of view when the information became available. We put in processes for all the Quality Assurance items and highlighted the risks inherent in testing under these conditions (including the lack of any understanding of the project) and went forward with that. We put a strong emphasis on what was required now in order to make this work.

  • A Better Way – Case Study 2 – Thinking Like the Client

    A Better Way – Case Study 2 – Thinking Like the Client

    In our last several blogs we have discussed ‘A Better Way to Test”.

    The issue is to apply this to actual situations. We have 5 Case Studies we plan to use over the next several weeks to address this. The second case study might be called “Thinking Like the Client”.

    Even though many in IT have embraced Agile in some form or another and with some level of success, not all clients are so willing. We find this particularly the case with larger, older and more safety or image conscious clients. They are not willing to take the risk of everything not coming together at the correct time. They are not willing to live with constant change. In addition, they often have milestones that need to be fulfilled and quite frequently they have stated contract deliverables that need to be fulfilled so that payments can be made.

    We received a call from the President of a development company with a large contract with probably the oldest, largest and most image conscious client you could get – the federal government. Even though the company had delivered projects successfully before and had a good record of coming through with what was required, the client still wanted a formal Test Plan completed.

    In our experience, the client is normally okay with a High Level Master Test Plan provided it contains the following (this is not an exhaustive list by any means):

    1. High Level Objectives
    2. A listing of the types of testing needed and the risk around each type
    3. Processes for Test Creation and signoff
    4. Processes for Defect tracking and resolution
    5. Methodologies for executing the testcases

    This reassures them that the developers have an understanding of what needs to be done.

    Take a look at some of the seminars that we offer that address this situation and see if they apply to you. Testing can be better.

  • Software Testing Strategy – The Test Strategy

     

    We discussed Test Plans and their contents in the earlier blog and today we will discuss the Test Strategy. Some people will look at the title above and think we are just repeating our blog from three weeks ago. Luckily, that’s not the case. We differentiate between Test Plans and Test Strategies.

    NVP considers a Test Strategy to be a document that outlines a long term direction for testing. It’s possible that the Test Plans for each project will borrow heavily from the Test Strategy and may even be based on it. We’re not necessarily considering that level of connection in this scenario.

    The following is a set of contents for a Test Strategy

    1. Introduction – outlines the purpose of the document
    2. Corporate Business Strategy – Copy and paste from the relevant business document
    3. A high level outline of the Test Strategy – See below
    4. Alignment with corporate strategy and identification of the gaps
    5. Baseline of current testing (where we are today)
    6. Gaps between the baseline and Test Strategy
    7. Goals or methodologies to close the gaps
    8. Strategy assessment process
    9. Continuous improvement

    The Test Strategy section would include answers to the following:

    1. Where is the best place to complete testing in the life cycle?
    2. Who are the best resources for each level and type of testing?
    3. What is the long term development process for the identified resources?
    4. From where are the resources going to be sourced?
    5. What is the long term automation process or direction?
    6. Where is the greatest ROI for testing?

    Some questions to assess your Test Strategy readiness:

    1. Do you have a Test Strategy?
    2. If you have a Test Strategy; has it been reviewed recently?
    3. Is there a person or a group responsible for the Test Strategy?

    If you answered No to any of the above questions, send us an email to see if a Test Strategy would be a fit for your organization.

  • Software Testing Strategy – The Test Plan

    Any given test plan and its contents vary widely depending on to who is doing the testing and what template is used. Test plans can be found anywhere on the web. They can be generic in nature or specific to a particular industry and have specific sections that are critical for regulatory or risk reasons. A test plan can also be seen as a strategy, while in some cases strategy is never considered. Sometimes test cases are included in a test plan.

    We consider a test plan to be a document that outlines a path for the testing but excludes the test cases (which we like to keep in a database). The test plan often includes the following (not a comprehensive list):

    1. Introduction
    2. Test Approach
    3. Assumptions and Dependencies
    4. Risks and the Risk Plan
    5. Schedule and Resources
    6. Glossary

    The Incredible Shrinking Test Plan

    We’ve seen where one client invested a lot of time creating a test plan template for use within their organization. The template with various sections indicated what the contents of that section should include, however, if the section was irrelevant,  a statement as to why it was inapplicable was to be noted. Under no condition was any section to be deleted. Unfortunately, one group misunderstood the importance of keeping ALL data and deleted any section they felt was unnecessary. They innacurately used the previous plan version as the template for the next one and so on. So every time a section was deleted it was lost forever. We used to refer to those plans as the The Incredible Shrinking Test Plan, it just got smaller and smaller.

      1. Do you write test plans?
      2. If you use a template, do you have trouble filling it out?
      3. Do you get test plans reviewed by the relevant stakeholders?
      4. Are they approved at any point?
      5. What is your experience in how well they test what you need to test?

    And most importantly: Do you ever review them after the project is over and see how well you adhered to the initial outline?

  • Examples of Verification in Software Testing

    In our last blog post, we included a list of Examples of Verification without going into too much detail. In this blog we will take a couple of those verification list items and expand on them. The examples of verification that most tend to impact software testers with the best return are Test Plans, Test Cases, Test Data and Test Results.

    Test Plans

    Applying verification techniques to a Test Plan can save hours of effort. The three methods we can use to review a test plan are:

      • Walkthrough – in this method, the author of the Test Plan ‘walks’ one or more of their peers through the test plan, explaining the sections and what is meant by the content. The role of the peers is to find problems, omissions, extra content, incomplete items, inconsistent items and to add things that they might feel were missed. The intent is to have a better document more accurately reflecting the needs of the project stakeholders. A new version is issued after all the errors are corrected and it is used going forward.
      • Document Review – In this method, a review committee (preferably selected from the interested stakeholders) reviews the documents and records the same items as listed above for the walkthrough. Once they are finished their individual reviews, they come together to create a final list of problems which need to be corrected. A new version is issued after all the errors are corrected and it is used going forward.
      • Inspections – In this method, formalized roles are defined and assigned and a procedure is followed to ensure proper inspection of the document. The intent and result is the same as the previous two methods. The only difference is the degree of formality.

    What’s the point in all of this? The payback from reviewing the plan (using any of the methods above, more than pays for itself in terms of less errors going forwrd, less work to be undone, redone and redone (again).
