The phrase "as a first test" is correct and usable in written English.
It can be used when introducing an initial evaluation or trial of something.
Example: "As a first test, we will measure the system's response time under normal conditions."
Alternatives: "as an initial assessment" or "as a preliminary test".

As a first test, we performed extensive numerical simulations of the studied setup to verify the presence of the EP in the complex eigenvalue surfaces explicitly (see Methods section).
As a first test PICUS v1.2 is applied to simulate equilibrium species composition spatially explicit in heterogeneous alpine landscapes at sample plots of the Austrian Forest Soil Survey along a transect through the Eastern Alps.
We then, as a first test, compare the database constructed using this methodology for years 2003 and 2005 with those obtained by other approaches previously used to cover and explore the nanotechnology dynamic.

To evaluate the proposed technique, increasing the effective multiplication factor Keff of a WWER-1000 core along flattening power with keeping power peaking factor below a specific limit as a first test case and flattening of power as a second test case are considered as objective functions; although other variables such as burn up and cycle length can also be taken into account.
As a first test of these new tools, we have chosen to model the recently developed convoluted moderator concept, in which a moderating material is interleaved with layers of perfect crystals to provide an exit path for neutrons moderated to energies below the crystal׳s Bragg cut off from locations deep within the moderator.
