assert_checkequal
Check that computed and expected are equal.
Syntax
assert_checkequal ( computed , expected ) flag = assert_checkequal ( computed , expected ) [flag,errmsg] = assert_checkequal ( computed , expected )
Parameters
- computed:
the computed result
- expected :
the expected result
- flag :
a boolean, %t if computed is equal to expected, %f if not
- errmsg :
a string, the error message. If flag==%t, then errormsg=="". If flag==%f, then errmsg contains the error message.
Description
Performs silently if computed and expected are equal.
For complex numbers: We compare first the real parts. In case of equality, we compare the imaginary parts.
Matching Nan values are always considered equal.
1/%z and 2/(2*%z) are not equal: For the time
being, Scilab does not normalize equivalent rationals.
In containers, matching void elements are considered equal.
If the comparison shows that computed is equal to expected,
if the errmsg output variable is not used, an error is generated,
if the errmsg output variable is used, no error is generated.
Examples
Tests with success:
assert_checkequal ( %T , %T ); [flag , errmsg] = assert_checkequal ( [%T %F], [%T %F] ); assert_checkequal ( %nan , %nan ); c = complex(1, %nan) assert_checkequal (c, c); assert_checkequal ( sparse(%nan) , sparse(%nan) ); assert_checkequal ( 2:$-1, 2:$-1 ); assert_checkequal ( ["abc" "" ascii([9 10 13])], ["abc" "" ascii([9 10 13])] ); assert_checkequal ( [gdf(), gda()], [gdf(), gda()]); assert_checkequal ( list() , list() ); assert_checkequal ( list(1,,3), list(1,,3) ); assert_checkequal ( list(1,,list(,4)), list(1,,list(,4)) ); assert_checkequal ( list(%nan,,7) , list(%nan,,7) ); sine = sin; assert_checkequal ( sin, sine ); cosinus = cosd; assert_checkequal ( cosinus, cosd ); assert_checkequal( iolib, iolib );
Tests with failure:
assert_checkequal ( %F , %T ); flag = assert_checkequal ( %F , %T ); // No error produced : [flag , errmsg] = assert_checkequal ( %F , %T ) assert_checkequal ( [1 2], [3 4] ) assert_checkequal ( 1 , [2 3] ) assert_checkequal ( 1 , "b" ) assert_checkequal ( "b", "B" ) assert_checkequal ( 1+%s, 1+%z ) assert_checkequal ( 1/%s, 2/(2*%s) ) assert_checkequal (list(2,,7), list(2,%F,8)); assert_checkequal ( [gdf(), gda()], [gdf(), gdf()] ); assert_checkequal ( sind, cosd ); assert_checkequal ( iolib, corelib );
