Test Driven Development (TDD) is more a development technique than a test technique. A developer may perform low level testing using the Test Driven Development, while a tester or product owner performs high level testing using Acceptance Test Driven Development (ATDD). Behavior Driven Development (BDD) can include both low level and high level tests.
Test Driven Development
Test driven development is a technique used to develop code guided by automated test cases. It is also known as test first programming, since test cases are written before the code. Test driven development includes:
The test cases written are primarily unit level and typically code-focused (white-box), though tests may also be written at the integration or system levels. Test driven development was popularized by Extreme Programming [Beck02] but is used in other agile methodologies and sometimes in sequential lifecycles. This development approach allows fixing coding defects as soon they are introduced.
Test driven development reduces the introduction of defects by helping the developer focus on the clearly defined expected results. The tests serve as a form of executed design specification for future maintenance efforts. The tests are automated and are used in continuous integration.

In addition to Foundation and Advanced Level exams, Expert Level Test Manager exams will be offered during ASTQB Conference 2014!
These Expert Level exams will be held for the first time ever. See more information at the ASTQB Software Testing Conference page.
The first Expert Level course "Improving the Testing Process - Module Assessing Test Processes" has started in Netherlands. See more information in www.bntqb.org
The agile project test strategy or test approach (the distribution of the test effort and coverage over the items to be tested) is defined during the planning event and included in the backlog. For example, during the planning stage, the agile team estimates, with the aid of planning poker, the size (often estimated in story points) for each story of a product backlog. Planning poker is the ideal way to formulate relative estimation size; i.e., where the estimations are related to one another. A reliable estimation is made by the whole team. By means of cards, everyone allocates story points to the estimated size of a backlog item. Aspects such as effort, complexity and the thoroughness of testing (in relation to the product risk) play a role in the estimation. Therefore, it is advisable to include the risk classification of a backlog item - particularly in the case of user stories - in addition to the priority specified by the product owner, before the planning poker is initiated. Differences in estimates are discussed, after which the card-playing is repeated until consensus arises. The discussion that produces this means of evaluation ensures that nothing is forgotten and that everyone is involved. This ensures a reliable estimation of the work — across the various disciplines — which is needed to complete a product item and to boost collective knowledge of what has to be done.

An important concept of any agile software development is getting reliable, working and integrated software at the end of every sprint or iteration. Continuous integration is a software development practice addressing this challenge by merging all changes made to the software and integrate all changed components regularly, at least once a day. Goal is to wrap compilation, build, deployment and testing into a single, automated and regularly repeatable process. Continuous integration can also be seen as a process in which developers integrate their work constantly, build constantly, and test constantly so errors in code can be detected more quickly.
A full continuous integration process consists of the following activities:
