  Understanding the applicability and limitations of electronic-structure
methods needs careful and efficient comparison with accurate reference data.
Knowledge of the quality and errors of electronic-structure calculations is
crucial to advanced method development, high-throughput computations, and data
analyses. In this paper, we present a test set for computational materials
science and engineering (MSE), that aims to provide accurate and easily
accessible crystal properties for a hierarchy of exchange-correlation
approximations, ranging from the well-established mean-field approximations to
the state-of-the-art methods of many-body perturbation theory. We consider
cohesive energy, lattice constant and bulk modulus as representatives for the
first- and second-row elements and their binaries with cubic crystal structures
and various bonding characters. A strong effort is made to push the borders of
numerical accuracy for cohesive properties as calculated using the
local-density approximation (LDA), several generalized gradient approximations
(GGAs), meta-GGAs and hybrids in \textit{all-electron} resolution, and the
second-order M\o{}ller-Plesset perturbation theory (MP2) and the random-phase
approximation (RPA) with frozen-core approximation based on
\textit{all-electron} Hartree-Fock, PBE and/or PBE0 references. This results in
over 10,000 calculations, which record a comprehensive convergence test with
respect to numerical parameters for a wide range of electronic structure
methods within the numerical atom-centered orbital framework. As an
indispensable part of the MSE test set, a web site is established
\href{http://mse.fhi-berlin.mpg.de}{\texttt{http://mse.fhi-berlin.mpg.de}}.
This not only allows for easy access to all reference data but also provides
user-friendly graphical tools for post-processing error analysis.
