Does a testament tell whether the deceased owned land and buildings?

The short answer is no, certainly for the pre-19th century period. In Scotland, an individual’s property was divided into two types, ‘heritable’ and ‘moveable’. The former consisted of land, buildings, minerals in the ground and mining rights, while the latter included the rest of his or her possessions, basically anything that could be moved. Testaments were concerned only with moveable property. Having said that, copies of some 19th century wills (alternatively named dispositions, settlements and latter wills and testaments), to be found in sheriff court registers may well include references to the deceased’s heritable property. However, since the rules of inheritance differed in respect of the two types of property (with records relating to the disposal of heritable property to be found elsewhere), you should not expect to find anything here.
