Member functions


Close()

IMPORT_C void Close();

Description

Closes the console and frees any resources acquired.


Title()

IMPORT_C void Title();

Description

Prints out the console title and version number.

The format of the text is:

RTEST TITLE: XXX YYY
Epoc/32 YYY

where XXX is the console title, and YYY is the version number, formatted as described by TVersion::Name().

Start()

IMPORT_C void Start(const TDesC &aHeading);

Description

Marks the start of a set of tests.

Note that sets of tests can be nested.

A call to this function must be matched by a call to RTest::End() to mark the end of this set of tests.

Parameters

const TDesC &aHeading

A heading describing the set of tests; this is printed at the console.

See also:


Next()

IMPORT_C void Next(const TDesC &aHeading);

Description

Marks the start of the next test.

Parameters

const TDesC &aHeading

A heading describing the test; this is printed at the console. This function is also called by Start(), which passes the text that describes the set of tests.

See also:


End()

IMPORT_C void End();

Description

Ends the current set of tests.

If this set of tests is not nested within another set, then a message reporting success is written to the console.

Panic codes

USER

84 if there was no matching call to RTest::Start(), i.e. more calls to End() have been made than calls to Start().

operator()()

IMPORT_C void operator()(TInt aResult, TInt aLineNum, const TText *aFileName);

Description

Checks the result of a condition and, if this is false, prints a failure message at the console and raises a panic.

Before checking the condition passed in, the operator increments a check number. This is a value that is set to zero at the start of a test and is incremented by this operator (and by all variants of it). It identifies the check being made within the current test. This value is printed on a failure message.

Typically, the operator is called, passing a test condition, for example:

RTest test(... heading text...,line number... file name)
TInt r;
...some operation to be tested that returns a value in r...
test(r==KErrNone);

The failure message has the format:

: FAIL : XXX failed check N in FFF at line Number: M
RTEST: Checkpoint-fail

where XXX is the console title, N is the check number, FFF is the filename, and M is the line number passed in.

Parameters

TInt aResult

The condition being tested. This is interpreted as a true or false value.

TInt aLineNum

A line number that is printed in the failure message if the condition being tested is false.

const TText *aFileName

A file name that is printed in the failure message if the condition being tested is false.

Panic codes

USER

84 if the condition being tested is false.

operator()()

IMPORT_C void operator()(TInt aResult, TInt aLineNum);

Description

Checks the result of a condition and, if this is false, prints a failure message at the console and raises a panic.

Before checking the condition passed in, the operator increments a check number. This is a value that is set to zero at the start of a test and is incremented by this operator (and by all variants of it). It identifies the check being made within the current test.

RTest test(... heading text...,line number)
TInt r;
...some operation to be tested that returns a value in r...
test(r==KErrNone);

The failure message has the format:

: FAIL : XXX failed check N at line Number: M
RTEST: Checkpoint-fail

where XXX is the console title, N is the check number, and M is the line number passed in.

Parameters

TInt aResult

The condition being tested. This is interpreted as a true or false value.

TInt aLineNum

A line number that is printed in the failure message if the condition being tested is false.

Panic codes

USER

84 if the condition being tested is false.
