You can define your required environment in a file. Default file is .envassert but you can use any file. . It is advantageous to use envassert for examnple when running a container. If you check your environment for missing or wrongly defined environment variables at the beginning of the container run, your container will fail sooner instead of in a later point in execution when the variables are needed.
