Companion object that facilitates the importing of Tables
members as
an alternative to mixing it in. One use case is to import Tables
members so you can use
them in the Scala interpreter:
Welcome to Scala version 2.8.0.final (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_22). Type in expressions to have them evaluated. Type :help for more information. scala> import org.scalatest.prop.Tables._ import org.scalatest.prop.Tables._ scala> val examples = | Table( | ("a", "b"), | ( 1, 2), | ( 3, 4) | ) examples: org.scalatest.prop.TableFor2[Int,Int] = TableFor2((1,2), (3,4))

For example, you could create a table of 5 rows and 2 colums like this:
import org.scalatest.prop.Tables._ val examples = Table( ("a", "b"), ( 1, 2), ( 2, 4), ( 4, 8), ( 8, 16), ( 16, 32) )
Because you supplied 2 members in each tuple, the type you'll get back will be a TableFor2
. If
you wanted a table with just one column you could write this:
val moreExamples = Table( "powerOfTwo", 1, 2, 4, 8, 16 )
Or if you wanted a table with 10 columns and 10 rows, you could do this:
val multiplicationTable = Table( ("a", "b", "c", "d", "e", "f", "g", "h", "i", "j"), ( 1, 2, 3, 4, 5, 6, 7, 8, 9, 10), ( 2, 4, 6, 8, 10, 12, 14, 16, 18, 20), ( 3, 6, 9, 12, 15, 18, 21, 24, 27, 30), ( 4, 8, 12, 16, 20, 24, 28, 32, 36, 40), ( 5, 10, 15, 20, 25, 30, 35, 40, 45, 50), ( 6, 12, 18, 24, 30, 36, 42, 48, 54, 60), ( 7, 14, 21, 28, 35, 42, 49, 56, 63, 70), ( 8, 16, 24, 32, 40, 48, 56, 64, 72, 80), ( 9, 18, 27, 36, 45, 54, 63, 72, 81, 90), ( 10, 20, 30, 40, 50, 60, 70, 80, 90, 100) )
The type of multiplicationTable
would be TableFor10
. You can pass the resulting
tables to a forAll
method (defined in trait PropertyChecks
), to perform a property
check with the data in the table. Or, because tables are sequences of tuples, you can treat them as a Seq
.
