Reused software has become such everyday tools that\nthere is a generation of software developers who have solely worked with a software framework, and have little to no understanding whats under the hood.\n\nThe world of third-party libraries and software frameworks has led to a design\npattern called \"Opportunistic Design.\" Typical traits of opportunistic design are\nthat developers copy and paste different code snippets from online and utilize different libraries and frameworks in a carefree manner, prioritizing convenience\nover a systematic and abstraction-driven approach. It is also typical that the developer does not fully understand the reused code, as a result of which unknown\nand unwanted side effects may arise in the developed software.\n\nThe thesis examines open-source projects developed in Go, employing statistical research methods, such as hypothesis testing, in order to study whether\nthere are implications of opportunistic design patterns within the ecosystem.\nThe study is conducted by measuring quality in the form of composite variables\ncollected from the metadata of version-controlled projects, calculating correlations between these variables, and used third-party code.\n\nFindings imply that opportunistic design patterns are not visible within the Go\necosystem. This is, however, not a generalizable result because programming\nlanguage ecosystems are only comparable to a degree.
