In addition, the Picture result of To_Picture is -- converted back to a picture string value using function Pic_String, -- and the result of function Blank_When_Zero is validated based on the -- value of parameter Blank_When_Zero used in the formation of the Picture -- by function To_Picture. -- -- TEST FILES: -- The following files comprise this test: -- -- FXF3A00.A (foundation code) -- => CXF3A02.A -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- 11 Mar 97 PWB.CTA Corrected invalid picture string and uppercase -- problem. --! with FXF3A00; with Ada.Text_IO.Editing; with Ada.Strings.Maps; with Ada.Strings.Fixed; with Report; procedure CXF3A02 is Lower_Alpha : constant String := "abcdefghijklmnopqrstuvwxyz"; Upper_Alpha : constant String := "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; function UpperCase ( Source : String ) return String is begin return Ada.Strings.Fixed.Translate ( Source => Source, Mapping => Ada.Strings.Maps.To_Mapping ( From => Lower_Alpha, To => Upper_Alpha ) ); end UpperCase; begin Report.Test ("CXF3A02", "Check that the function " & "Ada.Text_IO.Editing.To_Picture raises " & "Picture_Error if the picture string provided " & "as input parameter does not conform to the " & "composition constraints defined for picture " & "strings"); Test_Block: declare use Ada.Text_IO; use FXF3A00; TC_Picture : Editing.Picture; TC_Blank_When_Zero : Boolean; begin -- Validate that function To_Picture does not raise Picture_Error when -- provided a valid picture string as an input parameter. for i in 1..FXF3A00.Number_Of_Valid_Strings loop begin TC_Picture := Editing.To_Picture(Pic_String => Valid_Strings(i).all, Blank_When_Zero => False ); exception when Editing.Picture_Error => Report.Failed ("Picture_Error raised by function To_Picture " & "with a valid picture string as input parameter, " & "Valid_String = " & FXF3A00.Valid_Strings(i).all); when others => Report.Failed("Unexpected exception raised - 1, " & "Valid_String = " & FXF3A00.Valid_Strings(i).all); end; end loop; -- Validate that function To_Picture raises Picture_Error when an -- invalid picture string is provided as an input parameter. -- Default value used for parameter Blank_When_Zero. for i in 1..FXF3A00.Number_Of_Invalid_Strings loop begin TC_Picture := Editing.To_Picture(Pic_String => FXF3A00.Invalid_Strings(i).all); Report.Failed ("Picture_Error not raised by function To_Picture " & "with an invalid picture string as input parameter, " & "Invalid_String = " & FXF3A00.Invalid_Strings(i).all); exception when Editing.Picture_Error => null; -- OK, expected exception. when others => Report.Failed("Unexpected exception raised, " & "Invalid_String = " & FXF3A00.Invalid_Strings(i).all); end; end loop; -- Validate that To_Picture and Pic_String/Blank_When_Zero provide -- "inverse" results. -- Use the default value of the Blank_When_Zero parameter (False) for -- these evaluations (some valid strings have the '*' zero suppression -- character, which would result in an invalid string if used with a -- True value for the Blank_When_Zero parameter). for i in 1..FXF3A00.Number_Of_Valid_Strings loop begin -- Format a picture string using function To_Picture.
