## Description

## Details

### OilTest

    typedef struct {
    } OilTest;

An opaque structure describing how to test an OilFunctionImpl for an OilFunctionClass.

### OilTestFunction ()

    void                (*OilTestFunction)                  (OilTest *test);

Typedef for functions that initialize special values in source arrays for a particular function class.

`test` : | the `OilTest` structure

### OIL_TEST_HEADER

    #define OIL_TEST_HEADER 256

Default number of bytes that are prepended to the array test area.

### OIL_TEST_FOOTER

    #define OIL_TEST_FOOTER 256

Default number of bytes that are appended to the array test area.

### oil_test_new ()

    OilTest *           oil_test_new                        (OilFunctionClass *klass);

Creates a new OilTest for the OilFunctionClass represented by `klass`.

`klass` : | an OilFunctionClass
Returns : | the new OilTest

### oil_test_init ()

    void                oil_test_init                       (OilTest *test);

Intializes `test`.

FIXME: needs work

`test` : | the OilTest

### oil_test_free ()

    void                oil_test_free                       (OilTest *test);

Frees memory associated with `test`.

`test` : | the OilTest

### oil_test_set_iterations ()

    void                oil_test_set_iterations             (OilTest *test,
                                                             int iterations);

Sets the number of iterations of `test` to `iterations`.

`test` : | the OilTest
`iterations` : | the number of iterations

### oil_test_check_ref ()

    void                oil_test_check_ref                  (OilTest *test);

Runs the test specified by `test` on the reference function of the class being tested.

`test` : | the OilTest

### oil_test_check_impl ()

    int                 oil_test_check_impl                 (OilTest *test,
                                                             OilFunctionImpl *impl);

Runs the testing procedure described by `test` on the implementation `impl`.

`test` : | the OilTest
`impl` : | an OilFunctionImpl
Returns : | 1 if `impl` passes the test, 0 if it fails

### oil_test_cleanup ()

    void                oil_test_cleanup                    (OilTest *test);

Cleans up `test`.

FIXME: needs work
