This page describes the testing principles and schedule for release 6.0 of EiffelStudio.

When the release is out it should be reorganized to keep only the generic elements, release-specific material being moved to other pages.

OVERVIEW

A systematic testing process is necessary to produce a timely release with a high level of quality.

For the 6.0 release we have committed to a release date, 15 June 2007. The last six weeks of the release cycle are entirely devoted to testing. The general organization is described below.

At this level of the development all testing is performed by a team member other than the developer of the corresponding system or subsystem. The testing process is formalized:

  • For each system and subsystem, a test plan is created accordingly.
  • The test plan is made of a number of descriptions of tests to be run, each known as a Test Case Specifications (TCS). A TCS specifies a test scenario; it is not related to any particular execution of that scenario.
  • The testing process consists of running these test scenarios; the result of any such run is a Test Run Report (TRR).

You can find the corresponding documents for the 6.0 testing processes:

FINAL RELEASE PREPARATION PLAN FOR EIFFELSTUDIO 6.0

Phase 1: 1 week -- preparation

2 to 9 May 2007


Goal

  • For testers, to become familiar with tested product and put together a general plan of attack

General task (tester, with help of developer if needed):

  • Explore product, identify major functional areas, list TCS to be performed, start writing these TCS (the list should come first, then the texts themselves will be written as the testing effort progresses).

Outcome

  • List of TCS, each with at least S01 (id) and S08 (purpose)
  • Some fully written TCS themselves (as many as feasible)
  • Description of overall test strategy
  • Description of release (functionality, platforms...)

Rules

  • The tester can play around with the SUT, but is not expected to produce TRRs during this phase (although this is permitted).

Approval for bug fixes

  • Developer

Discussions between developer and tester

  • Permitted and encouraged, as long as the aim is to identify major areas requiring testing and understand how to use the SUT.


Phase 2: 3 weeks -- exploration

10 to 30 May 2007

Goal

  • To perform as many tests as possible, and fix problems as they are uncovered.

Tasks

  • Tester: finalize TCSs, perform extensive testing, fill in TRRs
  • Developer: as TRRs are sent, fix bugs

Outcome

  • TRRs (tester)
  • Bug fixes (developer)

Rules

  • During this phase all testing should be done with the official framework, i.e. apply a TCS (to be written as part of the process if it doesn't yet exist, e.g. if a bug is found when testing for something else) and produce a TRR.

Approval for bug fixes

  • Developer + Tester
(no commit without approval of tester, i.e. he has to re-run the TCS and authorize fix).

Discussions between developer and tester

  • Limited to exchange of TRRs (in particular, signaling those which indicate test failures) and anything that is strictly necessary. In general, minimize tester-developer interaction during this phase to ensure independence of testing.


Phase 3: 1 week -- consolidation

31 May to 6 June 2007


Goal

  • To finalize corrections, in particular of delicate aspects.

Tasks

  • Tester: check that all reported bugs have been fixed and that fixes work individually and together.
  • Developer: maintain integrity of SUT, consistency of fixes

Outcome

  • More TRRs
In particular, more TRRs reporting success for previously failing TCSs

Rules

  • Special care should be exercised during that phase. For any functionality that doesn't work a management decision has to be made to either urgently fix the problem or remove the functionality from the release.

Approval for bug fixes and any changes whatsoever

  • Developer + Tester + Lead engineer
(no commit without these 3 approvals)

Discussions between developer and tester

  • Permitted with no restriction, and encouraged. The goal is to get things right using all possible techniques. The more eyes the better (on all parts of the project) to find any remaining problems (which lead to either a fix or discarding functionality).

Phase 4: 1 week -- distribution

7 to 13 June 2007

Goal

  • To prepare the release

Tasks

  • Integration, compilation on different platforms, tests of installation procedure

Outcome

   Release 6.0 on platforms defined in advance (see Phase 1)
   (at a minimum Windows, Linux and Solaris)

Rules

  • Extreme care. No change except if critically needed. Normally at that stage no functionality should be removed, unless critical bug is found late in the process.

Approval for any changes whatsoever

   As in Phase 3.

Discussions between developer and tester

  • As in Phase 3.
