Open science platforms in support of data generation, analysis, and dissemination are becoming indispensible tools for conducting research. These platforms use informatics and information technologies to address significant problems in open science data interoperability, verification & validation, comparison, analysis, post-processing, collaboration, and publishing. Some fields such as biology have embraced and pioneered the use of open science platforms that have led to benefits across the discipline. Growing interest is gathering to apply these platform technologies to the fields of chemistry and electronic structure. In this dissertation, we present ESTEST (Electronic Structure Test) that is one of the first open science platforms developed for chemistry and electronic structure.
