Fusion Testing - Maximizing Software Test Execution
- 1. Fusion Testing Maximizing Test Execution By: James Tischart
- 4. Fusion F ocus – start your day with 15 minutes of thought U sage – how will your users work with the system S cope – decide on the scope of everything I nitiate – just go and explore O rganize – create a plan & be ready to deviate from it N ote – keep track of your exploration to retrace steps
- 12. Traceability Matrices Positives Negatives Can trace tests to requirement coverage Time consuming to create and maintain Displays what has been executed Often out of date and misleading Shows relationship between tests and features Duplicates information from test cases and requirements Provides defect traceability to features Dedication to frequent updates needed Do Don’t Tie your test lists to requirements or stories Trace to the test case or test idea Constrain your traceability to the feature level Try to trace to the functional level Build traceability into the automated tests Duplicate information in many documents Map automation to test lists or test specs Over complicate maintenance of multiple sources

Editor's Notes
- To provide information to the business about the risk of releasing a product to our customers. With this mission we can conclude that utilizing many different methods of testing will provide us with more of the data needed to make decisions. Our common goal should be empowering engineers to use their time to find all data possible and worry less about artifacts to present data. We need the engineers finding more data, through increased testing execution!
- F ocus : your day with 15 minutes of thought, what are your goals for the day or test focus, write them down Create a Goal for the day Map out how to reach that goal through test execution Determine the structure of testing needed Detailed Automated Exploratory Identify the environment or resources that are needed Discuss your plan with other team members Write down your items to Focus your day Be prepared to adjust your goals based on your exploration U se : how is the system under test going to be used by your customers (all customers) Create test persona’s of your customers to help you emulate product usage Work with your Product Manager’s, BA’s, and other team members to gather how the system is expected to be used Identify non-common usage scenario’s and analyze the risk to operations Review message boards to see what your customers are saying about the product and it’s usage Talk to your support personnel and review the usage tickets that don’t typically make it to engineering teams Organize a session with support to listen to the calls Take all of this knowledge and apply within the test checklists and other test structure Scope : what scope of testing do you need to accomplish, detailed structured testing, exploratory models How detailed does your testing artifacts need to be Understand performance needs and scale of the testing needed Mapquest Driving Directions (Structured Testing) Detailed Step by Step Once you reach a problem it is hard to route around Limits the number of paths to your destination Treasure Map (Exploratory Testing) Loser guidelines Provides a goal and guidelines on how to reach the goal Not all variables are the same leading to different paths Guidance System (Direct to Automation) Automate the exact steps Need both the details and the goal Variables need to be defined and specifically tested I nitiate : plan less and execute more, get your hands into the product and initiate different sequences to find more data Only plan at a daily level and then start testing Drive testing in different ways based on the information you gathered from your users Work with the other people on your team to cover more options Execute unexpected tests Write automation to help in your testing Talk to engineers about testing principles and initiate up front quality Initiate a discussion with the developer to learn the limits of the code, shoulder surf and bring up tests that they might keep in mind while developing Learn more about unit testing, testing methodologies, automation and products O rganize : have a plan, be ready to deviate from the plan based on the reaction of the system Take 10 to 15 minutes to organize your day Define your test needs and prepare them to maximizes your exploration Keep your work space organized to improve efficiency Prepare for your exploration by making note of possible diversions in your exploration Interrupt Scenario’s Failures Different Paths to the Same Goal Plan if you are going to time box your efforts Figure out how you will deal with interruptions in the day Identify any automation that can be execute to change the system state Understand your work schedule for the day, including meetings, breaks, social time, lunch and test focus Prepare a method to isolate yourself to immerse yourself in your work and let your peers and manager know that you are doing that N ote : It is important to be able to recreate your steps during your test execution Use a notepad to take notes while testing whether you are doing structured or exploratory testing If possible use a keystroke recording tool Note the key paths to your test exploration and when you find something unexpected retrace your notes to reproduce the problem Instrument your automation to make it easy to reproduce steps either manually or automated use your daily notes to update test checklists Share your notes with other testers or developers to communicate your findings Use notes to identify different paths regardless of a successful experiment of a failed experiment Notes can be translated into defect reports after reproduction and narrowing down the steps to failure
- Examples for each: Goals – Look to the Testing Types (Regression, Performance, Stability, Functional …) and decide what areas need to be covered for the project Methods – Determine the percentages of automation needed, structured tests needed and exploratory time needed Test Lists – see my blog for specific examples of test lists and the power that they can have Automate – Automation is one of the most misunderstood tools in the test arsenal (we often spend too much time automating and maintaining automation for the wrong things.) One of my automation engineers once spent 2 weeks on writing a set of automated tools for a piece of functionality that would only be around for 1 month focus instead on, performance and benchmark tests, but don’t automate just for the sake of automating, if there are tests that will only be run once and then are not valuable don’t spend time automating Document – our goal is to increase test execution, document plans, test results and metrics, however do not try to have low level details that require copious amounts of maintenance
- Example from Mx Logic on the Timeline and how I guided the team to fully using Fusion. 5 Phases – 1 st – Introduced Structured Testing 2 nd – Introduced Exploratory Testing (75% Structured, 25% Exploratory, 10 to 25% automation coverage) 3 rd – Introduced Automated Testing (50% Exploratory, 50% Structured, 50% automation coverage) 4 th – Combined Structured , Exploratory and Automation, introduced Fusion to Offshore Team, (75% Exploratory, 25% Structured, stopped maintaining a Test Management Tool, first introduction of Agile, 50% automation coverage) 5 th – Full Fusion implementation (test lists implemented, metrics fully supported, 90% Exploratory, 10% Structured, Direct to Automation, Offshore team doing exploratory and direct to automation, test tools covering traceability.) Currently in 5 th year of implementation – Defect Removal Efficiency increased from 30% to 95% over those 5 years Test team grew from 2 testers to 18 testers, while # of products supported grew from 1 to 6 Guide your team through change Organizations often need to flip teams and processes to get full benefit It is easier to remain entrenched in proven philosophies Relying on tried and tested artifacts can limit improvement Change Message creation Articulate why changing is necessary Growing complexity to testing requires more test execution Reduce inefficiencies to improve data collection Mentor your teams to help them understand Fusion The key to implementation is communicating Challenge the teams to increase test execution time Continuously inspect and adapt to improve implementation Train your engineering teams in different principles Static Test Techniques Structured Test Techniques Exploratory Test Techniques Automation Techniques Metrics need to be implemented Identify the metrics that can skew quality data (test case coverage, pass fail ratio’s) Track the amount of time your team spends on test artifact maintenance Track the amount of issues your customers are finding after release
- Use one of our UAT’s – The Tent and Party with the fun plan – had over 50 people do testing, found 5 showstoppers, 10 critical issues, and 10 usability issues
- Add funny story, that relates metrics and life, maybe about creating this presentation. No matter what methodology you implement in testing the interest will always lie in the data that can be presented to make business decisions from. How can you accurately assess quality when the combinations of test exceed the particles of the universe? Answer: You can’t, what you can do is present what you have tested, what you did not test, support the risk assessment used to order what was tested and what was not. Show the following on your report: # of Test Ideas Executed based on Risk Assessment # of Test Cases executed with pass fail ratios and a qualifier to the extent of coverage that those test represent # of Automation Test Pass & Fail Ratio – including how often those tests were run with their diminishing returns ratio Performance/Benchmark comparisons by build/iteration/release Engineering Team Quality Satisfaction Rating – an important measure is how the development and test teams feel about the quality and stability of the product, their gut feelings are often more indicative of risk and quality than any other measure Open bug count, not as overall percentage of bugs but as a data point on potential issues that your customers may face and report For detailed instructions on these metrics see fusiontesting.blogspot.com Find measures that represent quality & provide the most data Focus on customer impact with your metrics and look to improve those statistics # of Support Issues Raised per release. # of Patches by Sev per release % of Issues found by customers Automation Metrics % Pass/Fail Performance metrics Diminishing Returns New Coverage
- In most instances traceability matrixes or projects take up a majority of the document maintenance time. So how can you avoid this. First I am a supporter of traceability when it is scoped appropriately. It is very time consuming to maintain a detailed traceability matrix that maps every requirement to every test case through to every defect report. Instead look for opportunities to reduce the detail level Feature versus Functionality (often traceability goes beyond the feature level to the functionality of a feature so that any minor change to the functionality impacts the traceability.) Define traceability at the Feature level and worry about having test list items and automation at the functionality level. Test case level traceability (instead of trying to detail every test case, ensure that there is a test checklist for each feature and map your traceability at the checklist level, this way you do not need to update your traceability matrix with each change to a test case, and since there are fewer detailed test cases to map to you are mapping more to a test idea versus an actual test Defects – traceability of every defect is a manually intensive undertaking, instead of updating a matrix with the bug I design a bug system that is easy to track issues at a feature level. This way you can report traceability on a defect grouping level rather than a single issue level. For instance feature X has had a total of 20 defects logged with currently 2 severity 3 bugs open. Remembering that defect metrics are very misleading in the overall measurement of quality, they are just data points of what has been found not what has not been found. Automation – Again the devil is in the details with traceability on Automation, we absolutely need to know what is automated and what tests that automation executes as well as what the expectations are for the automation outcome, however mapping each automated test to each requirement, user story, user acceptance test etc can be a very large time expenditure that reduces the team’s efficiency on exploring and finding data, look for opportunities to tie your automation traceability into your test case traceability and the Feature or test checklist level rather than the individual test case level.
