|
-- OBJECTIVE:
|
27 |
|
|
-- Check that Ada.Text_IO.Editing.Put and Ada.Text_IO.Put have the same
|
28 |
|
|
-- effect.
|
29 |
|
|
--
|
30 |
|
|
-- TEST DESCRIPTION:
|
31 |
|
|
-- This test is structured using tables of data, consisting of
|
32 |
|
|
-- numerical values, picture strings, and expected image
|
33 |
|
|
-- result strings. These data tables are found in package FXF3A00.
|
34 |
|
|
--
|
35 |
|
|
-- The testing approach used in this test is that of writing edited
|
36 |
|
|
-- output data to a text file, using two different approaches. First,
|
37 |
|
|
-- Ada.Text_IO.Put is used, with a call to an instantiated version of
|
38 |
|
|
-- Function Image supplied as the actual for parameter Item. The
|
39 |
|
|
-- second approach is to use a version of Function Put from an
|
40 |
|
|
-- instantiation of Ada.Text_IO.Editing.Decimal_Output, with the
|
41 |
|
|
-- appropriate parameters for decimal data, picture, and format
|
42 |
|
|
-- specific parameters. A call to New_Line follows each Put, so that
|
43 |
|
|
-- each entry is placed on a separate line in the text file.
|
44 |
|
|
--
|
45 |
|
|
-- Edited output for decimal data with two decimal places is in the
|
46 |
|
|
-- first loop, and once the data has been written to the file, the
|
47 |
|
|
-- text file is closed, then opened in In_File mode. The edited
|
48 |
|
|
-- output data is read from the file, and data on successive lines
|
49 |
|
|
-- is compared with the expected edited output result. The edited
|
50 |
|
|
-- output data produced by both of the Put procedures should be
|
51 |
|
|
-- identical.
|
52 |
|
|
--
|
53 |
|
|
-- This process is repeated for decimal data with no decimal places.
|
54 |
|
|
-- The file is reopened in Append_File mode, and the edited output
|
55 |
|
|
-- data is added to the file in the same manner as described above.
|
56 |
|
|
-- The file is closed, and reopened to verify the data written.
|
57 |
|
|
-- The data written above (with two decimal places) is skipped, then
|
58 |
|
|
-- the data to be verified is extracted as above and verified against
|
59 |
|
|
-- the expected edited output string values.
