8.5. Ranges of Values

There are a few small differences in the Fit fixtures in FitNesse. For example, ColumnFixture tables in FitNesse can check number ranges.

Sometimes, we want to check that a number is less than some specified value rather than that it is a specific value. For example, Figure 8.5 tests that stress tests involving various numbers of clients react within a specified maximum time.

Figure 8.5. Checking Within Maximum

StressTest
clients	max reaction time	within time()
1	10	true
10	10	true
100	30	true
500	60	true

ColumnFixture provides a way to write this more directly, as shown in Figure 8.6. Instead of a number in the calculated column, we have a check that the result from the system under test with one client is less than 10 (<10).

Figure 8.6. Checking Within Maximum with <

StressTest
clients	reaction time()
1	<10
10	<10
100	<30
500	<60

We can also compare <=10, >10 and >=10 and check that a calculated number is within a given range. For example, 3 < - < 10 expects that the result in that cell, designated as -, is greater than 3 and less than 10.
