61 /*! \libinternal \brief
62 * Helper class for testing interactive sessions.
64 * The calling test can set the user input using setInputLines() (and possibly
65 * setLastNewline()), pass the streams from inputStream() and outputStream() to
66 * the code that executes the interactive session, and then call checkSession()
67 * after the session is finished.
68 * The input is provided from the array set with setInputLines(), and all
69 * output is checked using the reference data framework.
70 * The reference XML data can be viewed with the XSLT stylesheet to show
71 * exactly how the session went.
74 * \ingroup module_testutils
76 class InteractiveTestHelper
80 * Initializes the helper.
82 * \param[in] checker Parent reference checker to use.
84 * The helper creates a compound item under \p checker for the
85 * interactive session it tests.
87 explicit InteractiveTestHelper(gmx::test::TestReferenceChecker checker);
88 ~InteractiveTestHelper();
90 //! Sets whether the last input line contains a newline (by default, it does).
91 void setLastNewline(bool bInclude);
93 * Sets the input lines for the interactive session.
95 * Calls to TextInputStream::readLine() will return strings from this
97 * Newlines are added at the end automatically (except for the last
98 * line if `setLastNewLine(false)` has been called).
99 * If there are more `readLine()` calls than there are input lines,
100 * the remaining calls return end-of-input.
102 void setInputLines(const ArrayRef<const char* const>& inputLines);
104 //! Returns the input stream for the session.
105 TextInputStream& inputStream();
106 //! Returns the output stream for the session.
107 TextOutputStream& outputStream();
110 * Finalizes the checking for the session.
112 * This must be called after all input and output from a session has
113 * occurred, as the helper will not otherwise know when output after
114 * the last input has finished. This method also checks that the
115 * required number of input lines were read in the session.
