.SH NAME
test \- test-function in variational formulation (rheolef-7\&.2)
.SH "DESCRIPTION"
.PP
This class, and its associated \fCtrial\fP one, is used for test and trial functions involved in variational formulations\&. Variational formulations are specified by expressions of the C++ language\&.
.PP
A \fCtest\fP function is the formal argument involved in the expression for the \fBintegrate(3)\fP function: 
.PP
.nf
    geo omega ('circle');
    space Xh (omega, 'P1');
    test v (Xh);
    field lh = integrate (omega, 2*v);

.fi
.PP
 For a bilinear \fBform(2)\fP, the \fCtest\fP function represents its second formal argument, while its first one is referred to as the \fCtrial\fP one: 
.PP
.nf
    trial u (Xh);
    test  v (Xh);
    form a = integrate (omega, dot(grad(u),grad(v)));

.fi

.PP
This documentation has been generated from file main/lib/test\&.h
.PP
The \fCtest\fP and \fCtrial\fP classes are simply aliases to the \fC\fBtest_basic\fP\fP class:
.PP
.PP
.nf
typedef test_basic<Float,rheo_default_memory_model,details::vf_tag_01> test;
typedef test_basic<Float,rheo_default_memory_model,details::vf_tag_10> trial;

The \fC\fBtest_basic\fP\fP class provides an interface, via the \fBsmart_pointer(7)\fP class family, to a data container:
.PP
.PP
.nf
template <class T, class M, class VfTag>
class test_basic : public smart_pointer<test_rep<T,M> > {
public :
// typedefs:

    using rep  = test_rep<T,M>;

    using size_type      = typename rep::size_type;
    using memory_type    = typename rep::memory_type;
    using value_type     = typename rep::value_type;
    using scalar_type    = typename rep::scalar_type;
    using float_type     = typename rep::float_type;
    using geo_type       = typename rep::geo_type;
    using space_type     = typename rep::space_type;
    using diff_type      = typename rep::diff_type;
    using is_elementwise = typename rep::is_elementwise;
    using vf_tag_type      = VfTag;
    using vf_dual_tag_type = typename details::dual_vf_tag<VfTag>::type;
    using self_type        = test_basic<T,M,VfTag>;
    using dual_self_type   = test_basic<T,M,vf_dual_tag_type>;

// allocator/deallocator:
  
    explicit test_basic (const space_type& V) : base(new_macro(rep(V))) {}

// accessors:

    const space_type&  get_vf_space()  const { return base::data()\&.get_vf_space(); }
    static const space_constant::valued_type valued_hint = rep::valued_hint;
    space_constant::valued_type valued_tag() const { return base::data()\&.valued_tag(); }
    size_type n_derivative() const { return base::data()\&.n_derivative(); }

    size_type size() const { return get_vf_space()\&.size(); }
