+- unit tests of each function
+- Compare the parameter lists passed to the mars requests! (Regression)
+- Complete installation test with local sample webapi request before sending email 
+- test imports of gribapi, eccodes, webapi
+- test the types of parameters after controlfile /args reading and the checks
+- test complete extractions of a specific selection of cases -> are they fully extracted? 
+    * all final files in destination dir?
+    * contains each file the specified parameter?
+    * compare numerically....field per field?
+    * plot comparison? manually

+ Datensets: od, ei, ea, cera 
+ (je nach verfügbarkeit eta / gauss / omega )
+ -  jeweils: minimal grid (zb 1d, 1°), global, über Datumsgrenze
+ -  jeweils: grob/high resolution soweit möglich
+ - jeweils pro Datenstream!!!
+ - verschiedene zeitliche Auflösung
+ - public vs memberstate access
+ - 
+
+ - realistisches Datenset: OP, 0.1°, 60-137 , 20°N - 90°N, -180° - + 180°, jeweils eta und gauss
+ 
+
+
+
+Testdatensätze:
+- ERA5
+  - full resolution vs minimal resolution, testgrid
+  - 1h / 3h / 6h
+  - public vs member state
+  - eta
+
+- CERA
+  - full resolution vs minimal resolution, testgrid
+  - 3h / 6h
