How much testing does your release actually need?

Test strategy and test concept set what you test for, how deep you go and at which level. They also decide where residual risk is consciously accepted, and on what reasoning. We help you make those decisions in a traceable, project-specific way.

Why now

Four reasons for a thought-through strategy.

01

A strategic compass

Guidelines that reach beyond single projects and provide orientation when a decision has to be made under pressure.

02

Risk-based focus

Test depth follows the actual damage in case of malfunction and the likelihood profile of the component in question.

03

Consistent across test levels

Each level tests what it can secure most cheaply, with clear transitions between unit, integration, system and E2E.

04

Usable long term

A thought-through strategy carries across several projects and releases. The investment pays off from the third use onwards.

Strategic fields

Six areas that work together.

// 01

Test strategy

The umbrella document with principles that apply beyond single projects. Principles for prioritisation, test depth and quality goals at the organisational level.

// 02

Test concept

The implementation for a concrete project or release. Translates the strategy into concrete test objects, test data, tools and timeline.

// 03

Risk analysis

What can happen, how likely is it, how bad would it be? The answer drives test focus and decisions on test depth.

// 04

Test levels, test types & gate criteria

Unit, integration, system, acceptance, functional and non-functional. Each level catches defects where they are cheapest to resolve. Entry and exit criteria define when testing starts, ends and when it is aborted.

// 05

Coverage & prioritisation

What we test, what we explicitly do not, and why. Coverage is not an end in itself. The question is whether the risk is appropriately covered.

// 06

Test data & test environments

Realistic test data and clean environments are the invisible precondition for any sound test strategy. Where does the data come from, how is it anonymised, how do the environments cover real operating conditions?

Test level pyramid

Testing in layers.

E2E / UI

E2E / UI

Full user journeys through the entire application. Close to reality, but slow and maintenance-heavy, so deliberately kept low.

System

System

The whole system with all integrations, including external interfaces under controlled conditions.

Integration

Integration

Interplay between several components or services. Checks contracts and handovers inside the system, fast and targeted.

Unit

Unit

Individual functions or classes. Sub-second speed, deterministic, the basis for any sound suite.

Reference values. The actual mix depends on domain, risk and architecture, not on the pyramid as an end in itself.

Risk matrix

Which test depth for what?

Low likelihood
High likelihood
Impact
high
Watch

Rare but expensive

Targeted tests, risk-based prioritisation. A fit for exploratory sessions and focused integration tests on critical interfaces.

Critical

High attention

Comprehensive tests across all levels, manual and automated. The largest protection need sits here, this is where you do not save.

Impact
low
Minimal

Negligible

Smoke tests or consciously accepted residual risk. Just enough testing to catch the obvious without over-testing.

Automate

Daily territory

Frequent but cheap areas. Strong regression automation, firmly embedded in CI/CD.

The classification is per feature or component, not per project. A pragmatic three-step assessment is usually enough.

Method toolkit

What we work with.

Test strategy template

An umbrella document with principles, goals and ground rules for all projects in the organisation.

Test concept template

Project- or release-specific. Test objects, test data, timeline, tools.

Risk analysis canvas

Identification, assessment and focus in an iterable workshop format.

Test level guide

Decision support: which test belongs at which level, and why.

Coverage assessment

Risk-weighted rather than a pure percentage. Blind spots become visible.

Strategy review

A short check on whether the strategy still matches reality and goals.

Questions

What we are often asked.

Do we really need a documented test strategy?

For short-term single projects rarely. As soon as several releases, several teams or regulatory requirements are in play, a lean strategy pays off quickly.

What is the difference between test strategy and test concept?

The strategy is cross-project and long term, usually 2–3 years. The concept turns it into concrete actions for a specific project or release.

Does this fit agile teams?

Yes. The form becomes more iterative and aligned to the release rhythm. Strategy and test concept stay sound and grounded, they are continuously carried along instead of filed away once.

How long does it take to create?

The umbrella strategy and test concept take two to six weeks depending on complexity, including upstream analysis. After that both are continuously iterated and adapted to new projects.

Before the first test case. With a clear head.

Test strategy, test concepts and a risk-based distribution across test levels, worked out together with your team rather than handed over from a desk.
