This will help them to get started. It helps teams to get more connected as it shows the pain points where the collaboration isn't seamless. Adopting MTM can thus be a good start for agile teams to get testing aboard, but be aware the interactions are more important as tools. The tools won't fix bad collaboration, mismatching identities, lack of trust and won't give any reward. The previous tip "get a team" already explained the benefit of having testing knowledge onboard during the requirements gathering. Two practices are mentioned: assessing the test base and helping with acceptance criteria.

This tip is close to the second practice, when the team benefits from being able to capture acceptance criteria in logical test cases. During the release planning meeting, capture acceptance criteria and immediately add them as logical test cases linked to the product backlog item.

This will help the team to understand the item and clarify the discussion. An even more important benefit of this tip is that it helps testers be involved and be important at the early stages of the software cycle. With product backlog items you could use the following use story style for the description or title : -- As a [role] I want [feature] So that [benefit] You can use a similar format for acceptance criteria: -- Given [context] And [some more context] When [event] Then [outcome] And [another outcome] Acceptance criteria are written like a scenario.

SpecFlow see SpecFlow website [3] is a Behavior Driven Development tool that also uses this way of describing scenario's, from where it binds the implementation code to the business specifications. Tools can help to immediately create and link test cases to a backlog item.

Having them present for further clarification and ready to get physical specified with test steps. Visual Studio Process templates support this kind of scenario. It can also contain a linked test case.

The importance of teamwork in software development

Create them from the Tab 'Test Cases' and give them a meaningful title. You can re-use the logical test cases in Microsoft Test Manager by creating a sprint Test plan and add the backlog item to the test plan. The logical test cases will appear in your test plan, ready for further specification. Once I tried to implement this practice in a project the testers didn't agree. They were afraid the developers only would implement the functionality that was written in the logical test cases.

For them, knowing on forehand what was going to be tested seemed a bad idea for them. I had to work on Tip 1 first before the team could move forward. When there is no risk, there is no reason to test. So, when there isn't any business risk, there aren't any tests and is it easy to fit testing in a sprint. More realistically, a good risk analysis on your product backlog items before starting to write thousands of test cases is a healthy practice. The release plan establishes the goal of the release, the highest priority Product Backlog, the major risks, and the overall features and functionality that the release will contain.

Products are built iteratively using Scrum, wherein each Sprint creates an increment of the product, starting with the most valuable and riskiest. Product Backlog items have the attributes of a description, priority, and estimate. Risk, value, and necessity drive priority. There are many techniques for assessing these attributes. Product risk analysis is an important technique within the TMap test approach.

It not only helps the Product Owner to make the right decisions, but it also gives the team advantage in a later stage. Risk classification is invaluable while defining the right test case design techniques for the Product Backlog Item. Having a full product risk analysis for every Product Backlog Item during the Release Planning meeting is slightly overdone, but the major risks should be found. Determining the product risks at this stage will also provide input for the Definition of Done list. Within the Visual Studio Scrum 1.

This Work Item Type hasn't got a specific field for risk classifications. Adding a risk field is done easily. To integrate testing in a sprint, you should know the risks and use test design techniques that cover those risks, writing only useful test cases. In the same context as tip 3 you can think of regression tests sets. Some teams rerun every test every sprint, this is time consuming and isn't worth the effort. Having a clear understanding of what tests to execute during regression testing raises the return of investment of the testing effort and gives more time to specify and execute test cases for the functionalities implemented during the current sprint.

Collecting a good regression set is important. There are a lot of approaches how to get this regressions set, most of them are based on risk classifications and business value see the previous tip. The principle is that from each test case a collection of additional data is determined into the test cases for the regression test are 'classified'.

Using these classifications all cross-sections along the subsets of test cases can form the total tests that are selected. From TMap [4] " A good regression test is invaluable. Automation of this regression set is almost a must see next tip: test automation. Making a good selection which test cases to select is a trivial task. With excel you can do some querying for proper test cases but this gets harder when they are in different documents. Testing is more efficient if you have good query tools so you can easily make a selection and change this selection of the test cases are part of the regression run.

A team I supported had more than For the execution of a the regression set, a query needed to be run over all test cases to create a meaningful selection for the regression set. Test cases in Team Foundation Server are stored as work Item Types in the central database brings, which has powerful query capabilities. You can write any query you want, save it and use it for your regression test selection. The team I supported used query based test suites to save the selections.

Microsoft Test Manager has an interesting capability to control the amount of regression testing that need to be done during the sprint. A feature called "Test Impact", gives information about test cases which are impacted by code changes.

Achieving Quality Without a Dedicated Test Team

All validation activities test cost time and money. So, every activity to test a system should be executed as efficiently as possible see previous tips. Adding automation to the execution of these validations saves execution time, which saves money. But the creation and especially the maintenance of test automation cost time and money.

So, the hard question is "what and how should we automate for our system validations", where is the breakeven point of test automation in the project. The ROI of test automation is a challenge.

We have to think of how long is the test automation relevant in our project for example not all functional tests aren't executed every sprint, only a sub set, only the most important, see this post 'only meaningful tests' and how many times is the validation executed how many times over time and also on different environments. This gives us indications on how much effort we must put in our test automation.

Any other test automation tool will probably add his own value, but let's focus on Visual Studio levels. All these automation levels have an investment, and a maintainability level. The better you can maintain a test case, the longer you can use it for your ever evolving software system.

Teamwork and innovation

That is the connection between 'how long' and 'how well maintainable'. Another connection is the effort it takes to create the automation. The resulting benefit is that you can execute your script over and over again. The ideal situation: a test script with very small investment to create, used for a test that needs to be executed the whole life of the application and that doesn't change overtime.

No investment, no maintainability issues, maximum amount of executions. Result: maximum ROI. No need for maintainable test scripts, no automation investment. I have customers who use Microsoft Test Manager for test case management only, and they are happy with it. They maintain thousands of test cases and their execution, gathering information about the test coverage of the implemented functionality. In most situations, this is an ideal starting point for adopting Microsoft Test Manager and starting to look at test case automation.

As a test organization, you will get used to the benefit of integrated ALM tools that support all kind of ALM scenarios. Collecting an action recording takes some effort. You have to think upfront what you want to do, and often you have to execute the test case several times to get a nice and clean action recording. So there is some investment to create an action recording that you can reuse over and over again.

Teamwork and innovation

In Microsoft Test Manager you can't maintain an action recording. When an application under test changes, or when the test cases change, you have to record every step again. A fragile solution for automation. Find the test steps that appear in every test case, make a shared step of these steps and add an action recording to it.
