when working in pairs or groups. The cards we use seem to ful ll this purpose without being too complex or tiresome! We will go through each component of the card and justify its role. The name of the project is clearly needed if the story is to be related to a speci c application being developed by the company. It may be that a given story is used in several applications and while this is a sensible strategy, reusing previous components that have been successfully built, it does bring with it some dangers in that the story might have been slightly modi ed for a different context. We need to avoid confusion especially during maintenance. The name of the story is an essential component of the card! The date is also important a story might be revised during different sessions with a customer, and thus we need to be sure that we are using the most up-to-date version. Of course you should be using a suitable version control and management system to try to keep things in order. Most stories will relate to a speci c requirement; these were discussed in the previous chapter. The set of requirements and of stories will change over time, and it may be that we scrap some stories that are no longer needed and introduce new ones as the requirements change. An important issue and one that has no simple resolution is the amount of detail needed in a story. In practice, we should try to de ne stories so that their implementation and testing can be done within the natural timescale that we are working with this may be a day or a week or whatever the project needs and the programming team is comfortable with. The task description is a set of short sentences that describe in terms the customer can understand what the story does. Too much technical detail or jargon will confuse many customers. The quality attributes may seem an unnecessary ingredient at this stage, but there should be some reference to these. A number of problems we have experienced in the past have been caused by a lack of clarity about these constraints. It is often the performance of the software that is unacceptable (a Web page that loads too slowly) or

the usability of the story (e.g., a login facility that looks very different to what is expected). On the reverse of the card are the key issues relating to the resources needed to build and test the story. These resources include the date that the story is to be delivered this will be based on the time that the programmers estimate will be needed to build and test the story. The overall planning of the project will be a dynamic portfolio of stories and integrations that is adjusted as the project evolves, and the stories will be situated within this framework. The other information on the card assists in developing the tests. When writing tests, there are a number of important issues that have to be sorted out. Remember, we have no code yet, just the descriptions of the story. To run a test, we need to trigger the software with suitable inputs. These will be the subject of the rst component of the card. It might be that a direct user input causes the story to start or perhaps a speci c event or request from another part of the system accomplishes this. All of the expected inputs and events need to be identi ed. The next issue is the information that the story needs when triggered. Take the login story, for example; this receives a username and password and has to consult a lookup table or query a database to establish if the user s details are correct. This is the memory context that we need to set up for testing. Many stories will need such an environment for testing but not all. Naturally we will need to know what the expected behavior of the story is to tell whether it is correct. It is important that this is written down somewhere, that way we can convince ourselves and those that follow us that the tests were properly written. The next issue could be optional (some stories are more important than others). We have seen that the requirements can be clustered into mandatory, optional, and desirable so the same will be true of stories that relate to the requirements. However, there is another issue and that is the risk associated with a story. Some stories are critical in the sense that many others depend on them, and the system as a whole is threatened by failure of these stories. We should recognize this and give these stories some extra attention. Another type of risk is associated with the likelihood of the story being superseded by other stories as the requirements change. This allows the programmers and the customer to rationalize the order in which work is done maybe do the stories that are fairly stable rst, if that makes sense. Sometimes, however, you have to build some stories before they are stable in order to explore the overall architecture of the solutions and to allow for some interaction between different parts of the system and for testing purposes in the same way as you might write some scripts and stubs to help test partially built systems. Now we write some tests that will be expressed in terms of what is applied to the story, in what environment it is run, and the expected output. For example the login story (Figs. 5.5 and 5.6) will have a number of tests to explore, not only that it works in the way it should for legitimate users but also that unauthorized users are rejected and the number of rejections ts with the requirement. To do this, some temporary
