In implementation problems often arise when testers are never sure whether the software being tested has actually passed the test. This happens because there may be several execution paths that have never been tested. Testers must make every possible input data combination for testing. The selection of input data to find errors is a problem for testers because it has a high probability, so the test case design can automatically become a solution. In this implementation the application to be tested using black-box testing is the Mosque Management Information System. The Mosque Management application will be tested using black box testing where the test is only intended to see if the program matches the function desired by the program without knowing the program code used. To produce test case designs automatically in black box method software testing with equality partition technique. Equivalence Partitions technique is a test based on entering data on each form in the mosque management information system, each menu will be tested and grouped according to function whether it is valid or not.

The ease of switching operators is one of the serious challenges that must be faced by the telecommunications industry. To get new customers requires a much higher cost than maintaining existing customers. Customer churn refers to the periodic loss of customers in an organization. To retain existing customers, organizations must improve customer service, improve product quality, and must be able to know in advance which customers have the possibility of leaving the organization. By predicting customer churn, companies can immediately take action to retain customers. Prediction can be done by analysing customer data using data mining techniques. This study proposes to implement feature selection to select relevant features and can provide improved performance in customer churn prediction models. Some proposed feature selection techniques are Sequential Forward Selection (SFS), Sequential Backward Selection (SBS), Sequential Forward Floating Selection (SFFS), Sequential Forward Floating Selection (SBFS), Sequential Backward Floating Selection (SBFS). The classification algorithm used to classify is Naive Bayes. The model that provides the best performance value is the model that implements Sequential Backward Selection (SBS) and Sequential Backward Floating Selection (SBFS) feature selection technique with feature number 19.
