Data screening sometimes referred to as 34data screaming34 is the process of ensuring your data is clean and ready to go before you conduct further statistical analyses. Data must be screened in order to ensure the data is useable, reliable, and valid for testing causal theory. In this section I will focus on six specific issues that need to be
Testing Big Data application is more a verification of its data processing rather than testing the individual features of the software product. When it comes to Big data testing, performance and functional testing are the key. In Big data testing
Integration testing This identifies errors when the modules are integrated. Different methods for integration tests include 34bottomup34, 34top down34, and 34functional incremental34.
