Mechanics wiki / Survive the Storm / Test mode

Test mode

One switch in the mod turns on every convenience needed to test it quickly, then turns them all off again for normal play. It is a development aid only and is off in every shipped build.

What the switch changes

While test mode is on	Normal play	Test mode
Earth import cost and weight	As rebalanced	A tenth of both
Food import from Earth	Banned	Allowed
Old Food from Earth	Not orderable	Orderable
Food spoilage begins	Sol 15	Sol 1

Legend

One flag, all of it. A single flag in the mod drives every row above; there is no separate toggle per convenience. Turn it off and normal play is fully restored.
The tenth is uniform. Every resupply item - resources, prefabs, the Orbital Probe and the Drone - has its buy price and its weight cut to a tenth, so a test colony can be stocked in a few cheap, light rockets. The Supply Pod launch price is not part of this.
Old Food import is test-only. Old Food is a spoilage product, never a normal import; it appears in the resupply list only while test mode is on, priced to match Food.

Sources

Survive the Storm mod. The flag is StS_TEST_MODE in mod-survive/Code/StS_Common.lua; set it to false to ship. Each row is driven by one file: the tenth-price/weight scaler mod-survive/Code/StS_TestResupply.lua, the import ban mod-survive/Code/StS_NoFoodImport.lua, the Old Food import mod-survive/Code/StS_OldFood.lua, and the spoilage start mod-survive/Code/StS_FoodSpoilage.lua.
Every resupply item's price and weight is its CargoPreset[id].price / .kg, from which every reader recomputes (external/SurvivingMars/Lua/ResupplyItems.lua:19-72), so the scaler edits those two fields on every Cargo preset.
