A minimum viable test strategy is a lightweight way into testing that a team works out together: not a hundred-page document, but a shared map of test levels, test types, roles, tools, environments and metrics. It builds a common understanding, turns open questions into backlog items and gives teams something they can start working with right away.
Key Takeaways
- A minimum viable test strategy comes out of collaborative workshops, not documents. The result is a shared view of testing that teams can act on immediately.
- Test levels such as the microservice level or the product level have to be redefined for your own architecture, because classic level models often don’t fit modern system architectures.
- The most dangerous moment in a test strategy workshop is quick agreement, not conflict. Agree too early and you skip gaps that get expensive later.
- Agile projects routinely push non-functional requirements such as security and performance to later sprints, even though that risk should be a conscious, documented decision.
- A table of test levels, test types, roles, tools, environments and metrics exposes contradictions that go unnoticed in long test strategy documents.
What a Minimum Viable Test Strategy Is
The idea borrows from the minimum viable product: a test strategy that is just complete enough for a team to start testing, without waiting for a finished document. Instead of a fully written strategy, you get a starting point that deliberately leaves gaps and grows over time.
What separates it from the classic version is the mindset. A classic test strategy is written by one or two people over several weeks, sometimes reviewed for years, and in the end nobody reads it. A minimum viable test strategy gives the team the shared understanding it needs to get going, plus a backlog for everything still open.
Kathrin Potzahr sums up the goal like this: not the complete concept, but enough to get a continuous learning process started. If there is nothing, nobody can improve continuously. With a first version, they can.
Why the Classic Test Strategy Breaks Down in the New World
Classic test strategies fit modern architectures poorly because they were made for a different world. A typical case: a program is moving from monolithic applications to microservices, the cloud and agile development. The old world is well documented. For the new one, nobody knows how testing should work.
The problem shows up as soon as you get to test levels. People coming from the old way of thinking see applications as the test level first. In a microservice context, though, the service is the unit of deployment and has to be tested as such. On top of that you need a product view, because one product can be made up of several services.
Then there is the legacy world, which isn’t going away. Surrounding systems that are deployed only twice a year are still connected to the new services. A good test strategy has to show both worlds side by side instead of pretending only the new one exists.
How Test Strategy Storming Works
Test strategy storming applies the idea behind event storming to the test strategy: a collaborative workshop with sticky notes instead of a document written by one person on their own. The format is deliberately lightweight. It takes shape in the room, not in the preparation.
At its center is a table that serves as a test map. Its axes are test levels and test types, and the cells fill up with notes: responsible roles, tools, environments, metrics. Wherever knowledge is missing, a note marks an open point. The workshop doesn’t produce a finished concept, but it gives a clear picture of where things are stuck.
In practice, three workshops in a row were enough. The important part is to start with an empty table, not with prepared cards. The first question is simply: which test levels do we need? The first entry is usually a no-brainer like unit testing. After that, the real discussion begins.
The Discussion Is the Result, Not the Obstacle
Friction in the workshop isn’t wasted time. It is where the value lies. Trying to draw the line between a service and a product leads to long discussions. The exact definition matters less than the outcome: everyone ends up with the same picture of what a deployment unit is and what belongs at the product level.
Formal classifications don’t have to be textbook-correct either, as long as the team is happy with them. You can argue that consumer-driven contract tests are a test type, because they check interoperability. If the people involved would rather treat them as a test level, that stands. Shared understanding counts, not the right pigeonhole.
And this is where a surprising risk hides. A team that agrees too quickly is in more danger than one that argues for too long.
“I think it’s much more dangerous for people to agree quickly than for them not to agree.”
(Kathrin Potzahr)
Why the Facilitator Needs to Know Test Strategy
A test strategy storming session needs a facilitator with a testing background, because their main job is to ask questions. Someone who only walks the group through the agenda lets premature agreement slip through. Someone who knows the subject keeps probing: aren’t you missing something? Is that really how it is, or is it just a habit from the old world?
That challenging role matters more than speed. Many facilitators have the reflex to get through as fast as possible, and that misses the point. It is better to think broadly and get the map complete. It will get smaller and more specific later anyway, in the individual tasks.
If a team does get lost in details, basic facilitation technique helps: close the topic, put up a note marking the open point and move on. The detailed discussion can wait without the information getting lost.
Who Should Take Part in a Test Strategy Workshop
Test strategy storming only works with the right participants, and nobody outside the project can dictate who they are. As with event storming, the value depends on who is in the room. Agile projects often know only developers, Scrum Masters and Product Owners. Large programs have more roles that need to be involved.
There is no fixed rule, but there are two constants. The teams who will do the testing work later must be represented. And ideally someone with a product perspective sits at the table. The teams can’t all attend in full, though. A workshop with a hundred people breaks the format.
One setup that worked well included architects, test managers, operations and security experts. Depending on the context, you add project or program managers, people from the build infrastructure or, in a scaled environment, a system team. There is no single recipe. Involving the teams is not negotiable.
Which Components Belong in a Testing Strategy Map
The test map has two axes and four kinds of content per cell. Test levels and test types form the grid, and the cells hold roles, tools, environments and metrics.
| Component | Role in the Map |
|---|---|
| Test levels | Which levels get tested, from unit to microservice to product and integration |
| Test types | Functional, load and performance, security, usability, operability |
| Roles and responsibilities | Who does the work: development team, PO, test department, specialists |
| Tools | Which tool, often with one or two options where standardization is wanted |
| Environments | Where tests run, including external dependencies |
| Metrics | What gets measured, such as code coverage, at first without a fixed target |
The roles decide whether the strategy holds up. If the map itself still contains open work, it has to be clear who picks it up. Otherwise the backlog stays a wish list with no one to deliver it.
The test types are usually the more stable part, because they barely change when the architecture changes. They are still worth challenging. Is robustness a test type of its own or part of functionality? Is maintainability handled separately or as part of unit testing? Questions like these sharpen the shared picture.
Metrics First, Target Values Later
A minimum viable test strategy names the metric first, not the target value. It is enough to agree that code coverage will be measured. Whether 80, 75 or 90 percent is right becomes clear later, from experience.
It’s a deliberate method. You start with a value, watch whether problems come up and adjust. Maybe 90 percent fits in one case and 75 in another. Without a first version, there is nothing to base that improvement on.
Where requirements aren’t clear enough yet, as is often the case with load and performance, mark the point as open. Clarify the requirements first, then derive the metric from them. Keeping it honestly as an open point beats writing down false precision.
Otherwise Non-Functional Requirements Slip Down the List
A visible map keeps non-functional requirements from being forgotten. In agile projects, teams focus hard on features and push security, performance or usability further back. That doesn’t happen out of ignorance. It happens out of focus.
Postponing on purpose is legitimate. Postponing without noticing is dangerous. If you know security-relevant requirements exist, you can decide: not critical yet for an MVP with a small group of users, indispensable later. Three sprints with libraries full of security holes are manageable if the product only goes live after twenty sprints. What matters is that the decision is made consciously.
That is exactly what the visualization helps with. It keeps the non-functional properties in view, even if they only come into play late in the test levels.
From the Map to Backlog Items
After the workshop, the map is shown to the teams, and the open points turn into backlog items. A big table covered in sticky notes isn’t glossy, but it is easy to follow. Teams can see where they are involved and what is expected of them.
Anyone who was only represented in the workshop can still add requests and changes at this stage. After that, the teams know their tasks. The open notes become concrete backlog items that someone has to move forward.
In one case, an architects’ guild took this on. It made testing its own task, carried it into the teams and put it into practice in the pilot projects. In more formal environments, a written test strategy will still follow later. The hope is simply that it gets lived and adapted instead of ending up as a hundred unread pages.
Visualization Reveals What Stays Hidden in Prose
The test map works without a big workshop too, as a way to review existing test strategies. Long documents can be transferred into the same grid, and that brings out what you miss when reading.
One example: a project had two test strategies, one for the acceptance test and one for the stage before it. Only when both were transferred into the visualization did the breaks become visible. Different terminology, partly conflicting goals, everything that was spread out and hidden across the pages.
That is the reusable core of the method. The map forces scattered statements into a structure where contradictions can no longer slip through. Whether you are building a new strategy or taking stock of an old one, the picture shows more than the text.
Frequently Asked Questions
Why Do Long Test Strategy Documents Fail in Practice?
Because they fail in the creation process, not because of their content. A traditional strategy document is written by one or two people over the course of weeks; the coordination process sometimes drags on for years, and in the end, no one reads it. The lightweight alternative, on the other hand, provides a collaboratively developed framework that teams can use to start testing immediately, plus a backlog for everything that’s still pending.
Do traditional test levels still apply to microservice architectures?
Only to a limited extent. Those coming from the monolithic world initially view applications as the test level. In the microservices context, however, the service is the deployment unit and must be validated as such, supplemented by a product perspective, because a product consists of multiple services. Added to this is the legacy world: peripheral systems that are deployed only twice a year remain connected to the new services.
How many workshops does it take to create an initial shared test framework?
In practice, three consecutive workshops were sufficient. We don’t start with pre-made cards, but with a blank table whose axes represent test levels and test types. The first question is: Which test levels are actually needed? The first entry is usually a no-brainer, like unit testing; the real discussion begins after that.
Is it a bad sign if a team spends a long time arguing over definitions?
No. The friction is the real value of the workshop, not a waste of time. Quick agreement is more dangerous: Those who agree too soon overlook gaps. Even formal classifications don’t have to be perfect. Consumer-Driven Contract Tests can be justified as a test type, but they can remain as a test level if the team is satisfied with that.
Who should participate in a test strategy workshop?
The teams that will later perform the testing work must be represented by delegates, and ideally, someone with a product perspective should be at the table. A proven lineup has included architects, test managers, operations and security experts, and, depending on the context, program managers, people from the build infrastructure, or a systems team. Full teams of a hundred people throw the format off balance.
Should target values for test metrics be set immediately?
No; first, the metric is identified, not the target value. It is sufficient to specify that code coverage will be measured. Whether 80, 75, or 90 percent is appropriate is determined by observation during operation. Where requirements are still unclear (such as load and performance), the point is marked as open rather than assigned a value with false precision.
Why do security and performance get left behind in agile projects?
It’s a matter of focus, not ignorance: Teams concentrate on features and push non-functional requirements to the back burner. Deliberate deferral is legitimate; unconscious deferral is dangerous. Three sprints with libraries full of security vulnerabilities are manageable if the product doesn’t go live until after twenty sprints. The visual map keeps such characteristics in view so that decisions can be made consciously.
Can an existing test strategy be evaluated using the test map?
Yes, the map works as an inventory tool even without a large workshop. Long documents are transferred into the same grid, revealing inconsistencies that remain hidden when reading. In a project with two test strategies (one for acceptance testing and one for the stage preceding it), this revealed differing terminology and, in some cases, conflicting goals.
