A new approach to the problem of optimal software testing time is described. Most models implicitly assume the testing is terminated at the end of a prescribed period of time without user's approval. It means the release time and the in-service reliability are determined unilaterally by the developer. If software developer uses and maintains it, the assumption is appropriate. But, it may be inappropriate, if a software requiring more stringent reliability is developed by second party on a contract basis. In this case, the time of release is usually determined with the user's approval. To overcome the weaknesses of the assumption, a two stage testing with failure-free release policy is proposed. A software, after being tested by the developer for some time (in-house testing), is transferred to acceptance testing performed jointly with the user. During the acceptance testing, it is released when τ. units of time specified by user is observed to be failure-free for the first time. The policy may be attractive to a user because he can determine the time of release, and extend the testing time by increasing τ. A software cost model for the policy is developed. For the software developer, an optimal in-house testing time minimizing software cost, and various quantities of interests, such as expected periods of acceptance testing, are derived based on the Jelinski-Moranda software reliability model. Finally, numerical examples are shown to illustrate the results.
