The Classical Method of soil testing for consolidation was developed by Karl Terzaghi. Consolidation occurs when a pressure is applied to a soil whereby water is squeezed out but the space is not replaced by air.
There are a large number of soil tests related to construction:Particle Size Distribution test - finds the relative proportions of differing grain sizes within a soilAtterberg Limit test - used to establish the plasticity class of the soilCompaction test - used to find the optimum moisture content to achieve a maximum densityConsolidation / Oedometer testing - used to establish the settlement potential of a fine grained soil.Direct Shear test - used to measure the peak (and potentially residual) shear strengths of a soil. When tested at varying confining loads can be used to find the shear strength parameters Phi' and c'*Triaxial testing - used to find the elastic properties of the soil (Young's Modulus and Poisson's Ratio) along with the shear strength. These may be either drained or undrained tests.Constant and falling head permeability tests - used to establish the hydraulic conductivity / coefficient of permeability for coarse and fine grained soils respectively.*Note in the UK c' is assumed to be zero for design purposes, in other countries small non zero c' may be used.
The pumping out test can be used to measure the average k value of a stratum of soil below the water table and is effective up to depths of about 45m . A casting of about 400mm diameter are put down on radial lines from the casting, and both the casting and the observation wells are perforated to allow easy entrance of water. the test consist of pumping water out from the central casting at a measured rate (q), and observing the resulting draw down in ground water level by means of the observation wells.

The link between CBR and bearing capacity if you get figures in CBR how can you link them to the bearing capacity in kPa, this is the link in soil testing.

The plural of soil test is soil tests. As in "soil tests were carried out at the incident site".

There are soil test kits that are electronic and measure the soil levels. There are also soil test kits that use the small amounts of your garden soil and mix with the testers ingredients to read the levels.
macro and micro mutrients test in soil through FTIR
you test the soil to check how much PH it has. plants need the right PH
