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.

If no testing is done on the system, the quality of the system cannot be known so that if an error occurs it can harm the system. By conducting experiments can find the location of defects in a system that can be known from the beginning that can be fixed immediately. Testing there are several types of system experiments, experiments used are black box testing using a limit value analysis method that is effective in trying the functions of a system. The technique determines the limits on the lower and upper values to produce the actual values. Based on the test results using the boundary value analysis technique that still has a disability that is the lack of data verification, then there must be an improvement in the validation function.

Data validation process that has not been maximized can result in data that is stored in the database is not appropriate, including the login process that becomes an error. This can be detrimental to the owner and user in using this application. Therefore, it is necessary to improve the quality of validation more accurately, so that it can help the owner in the accuracy of the data. Applications that are designed in such a way must go through a testing phase to ensure the quality of the software itself. A good test case is if the test has the possibility of finding an error that is not revealed. Among the many ways of testing Black Box, in this study the Equivalence Partition testing method was chosen. This method tests solving or dividing the input domain from the program into data classes so that a test case can be obtained, which is considered quite relevant to test sales applications at PT Arap Store. Stages of research carried out begins by determining the functionality to be tested, designing test scenarios, determining the data to be tested, determining input can be numeric values, range values, related value collections or Boolean conditions in accordance with the database structure that has been created, conducting experiments testing, documenting research results, and drawing conclusions. Based on the results of tests that have been carried out, it gives a conclusion that this software can be used properly, after a repair has been made on the errors found. However, this test can be said to be imperfect, because it is only done by using several sample forms. From the results of this test it is expected that the application can be used according to user requirements.
