While SQL engines are now capable of detecting a large number of syntactic mistakes, most often semantic errors are not detected, which can lead to serious performance issues or even security vulnerabilities being introduced in the system. This thesis proposes a set of 25 validated heuristics together with a new rule-based static analysis tool for detecting the most common types of semantic bugs in SQL queries, based on evidence from previous research.

The most common reason for Continuous Integration (CI) build failures is failing tests. When a build fails, a developer often has to scroll through hundreds to thousands of log lines to find which test is failing and why. Finding the issue is a tedious process that relies on a developer’s experience and increases the cost of software testing. Providing CI build test results with additional context in the developer’s local development environment could help solve failing tests more quickly.

Software development is more and more reliant on external code. This external code is developed, bundled into packages and shared using package repositories like crates.io or npm. Reusing shared code bundles greatly improves development speed but without proper care and knowledge of included external code it can cause issues as well. Over-reliance on simple trivial packages that can be easily implemented locally can cause severe consequences like not being able to build if the package is no longer available.

Agile originated as a method to be used by a small number of co-located teams. When the amount of teams and the distance between the teams becomes bigger, issues will start to arise. With the rise of the computer and internet, programming-related work environments have become very large and globally distributed, implying a friction when using agile in these environments. This study aims to explore what challenges occur when using agile in very-large globally distributed environments and explore for practices that can be used to deal with them.

Software maintenance is an important and time consuming task during the software development cycle. Readability of test code is a crucial element for performing programming tasks, such as testing, bug fixing and maintaining code. Hence poorly written tests are difficult to maintain and lose their value to developers. In order to overcome this problem, we need to understand how programmers read test code. Therefore in this paper we conducted an empirical study to analyse the various reading patterns in novices and professionals using a sophisticated eye tracking device.
