The Reporter

To produce reports for use in the Inform user interface app.

§1. About reports.This whole section applies only for the non-standard use case where Intest is running inside the Inform user interface app. A "report" is then an HTML page summarising the results of testing, which that app can then display. Reports are heavily tied to the standard recipe for testing Inform source, when it's run through I7, then I6, then executed to obtain a transcript of the resulting play. As a result, any individual test can fail in a set number of ways:

define I7_FAILED_OUTCOME 1  I7 issued problem messages
define I6_FAILED_OUTCOME 2  I6 issued error messages
define CURSED_OUTCOME 3  where there's no ideal transcript to compare against
define WRONG_TRANSCRIPT_OUTCOME 4  the actual transcript didn't match the ideal
define PERFECT_OUTCOME 5

§2. Report feature.The following implements the -report command line feature.

void Reporter::report_single(OUTPUT_STREAM, test_case *tc, action_item *ai) {
    report_state rs;
    Initialise the report state2.1;
    TextFiles::read(rs.prototype_HTML_file, FALSE, "can't open test report file", TRUE,
        &Reporter::filter, NULL, &rs);
}

§3.

typedef struct report_state {
    text_stream *REPORT_TO;
    struct test_case *test;
    int success_code;  one of the *_OUTCOME constants above
    int turns_keyed;  number of commands auto-entered from a TEST ME
    struct filename *prototype_HTML_file;  ultimately from the app
    struct text_stream *relevant_node_ID;  to provide in-app links to the Skein
    int stage;  where we are in scanning the prototype
    int first_flag;
    int last_flag;
    char test_case_letter;  'A' to 'Z': for cases in an extension project
} report_state;

The structure report_state is private to this section.

§2.1. Initialise the report state2.1 =

    rs.test = tc;
    rs.success_code = ai->assoc_number;
    rs.turns_keyed = ai->assoc_number2;
    rs.prototype_HTML_file = ai->assoc_file1;
    rs.relevant_node_ID = ai->assoc_text;
    rs.stage = 1;
    rs.first_flag = FALSE;
    rs.last_flag = FALSE;
    rs.REPORT_TO = OUT;
    if (tc->letter_reference >= 1)
        rs.test_case_letter = (char) (((int) 'A') + tc->letter_reference - 1);
    else
        rs.test_case_letter = 0;

This code is used in §2.

§4. So, then, the following filter is run line by line on a prototype HTML file nominated by the UI app. We will splice in our report.

void Reporter::filter(text_stream *line_text, text_file_position *tfp, void *vrs) {
    report_state *rs = vrs;
    text_stream *OUT = rs->REPORT_TO;
    match_results mr = Regexp::create_mr();
    if (Regexp::match(&mr, line_text, U" <!--CONTENT BEGINS-->")) {
        WRITE("<!--INTEST REPORT BEGINS-->\n");
        rs->stage = 2;
    }
    else if (Regexp::match(&mr, line_text, U" <!--BANNER BEGINS-->")) rs->stage = 3;
    else if (Regexp::match(&mr, line_text, U" <!--HEADING BEGINS-->")) {
        rs->stage = 4;
        Insert test report header4.1;
    } else if (Regexp::match(&mr, line_text, U" <!--HEADING ENDS-->")) rs->stage = 5;
    else if (Regexp::match(&mr, line_text, U" <!--BANNER ENDS-->")) rs->stage = 6;
    else if (Regexp::match(&mr, line_text, U" <!--PROBLEMS BEGIN-->")) {
        rs->stage = 7;
        Insert additional material4.2;
    }
    else if (Regexp::match(&mr, line_text, U" <!--PROBLEMS END-->")) rs->stage = 8;
    else if (Regexp::match(&mr, line_text, U" <!--CONTENT ENDS-->")) {
        rs->stage = 9;
        Insert test report footer4.3;
        WRITE("<!--INTEST REPORT ENDS-->\n");
    } else {
        if ((rs->stage == 1) || (rs->stage == 2) || (rs->stage == 3) ||
            (rs->stage == 5) || (rs->stage == 9) ||
                ((rs->stage == 7) && (rs->success_code == I7_FAILED_OUTCOME)) ||
                ((rs->stage == 7) && (rs->success_code == I6_FAILED_OUTCOME))
            )
            Filter existing report, adjusting links4.4;
    }
    Regexp::dispose_of(&mr);
}

§4.1. Insert test report header4.1 =

    if ((rs->success_code == PERFECT_OUTCOME) || (rs->success_code == CURSED_OUTCOME))
        WRITE("<div class=\"headingpanellayout headingpanelSucceeded\">\n");
    else
        WRITE("<div class=\"headingpanellayout headingpanelFailed\">\n");
    WRITE("<div class=\"headingtext\">");
    HTML_OPEN_WITH("span", "class=\"headingpaneltext\"");
    WRITE("Example ");
    if (rs->test_case_letter) WRITE("%c: ", rs->test_case_letter);
    WRITE("&#8216;%S&#8217;: ", rs->test->test_case_title);
    switch (rs->success_code) {
        case WRONG_TRANSCRIPT_OUTCOME: WRITE("Failed"); break;
        case PERFECT_OUTCOME: WRITE("Succeeded"); break;
        case CURSED_OUTCOME: WRITE("Partly Succeeded"); break;
        default: WRITE("Couldn't Test"); break;
    }

        Insert link to transcript4.2.1;

This code is used in §4.

§4.2.1. Insert link to transcript4.2.1 =

    if (rs->test_case_letter) WRITE("?case=%c", rs->test_case_letter);

This code is used in §4.2 (three times).

§4.3. Insert test report footer4.3 =

    WRITE("<p></p>\n");

This code is used in §4.

§4.4. Filter existing report, adjusting links4.4 =

    WRITE("%S\n", line_text);

This code is used in §4.

§5. Combine feature.The following implements the -combine command line feature. Essentially it takes a batch of reports made by -report and merges them together.

void Reporter::combine(OUTPUT_STREAM, int count, filename *base_filename) {
    for (int i = 1; i <= count; i++) {
        report_state rs;
        Initialise the report state for combination5.1;
        TextFiles::read(rs.prototype_HTML_file, FALSE, "can't open test report file", TRUE,
            &Reporter::combine_filter, NULL, &rs);
    }
}

§5.1. Initialise the report state for combination5.1 =

    rs.test = NULL;
    rs.success_code = -1;
    pathname *P = Filenames::up(base_filename);
    TEMPORARY_TEXT(NEWLEAF)
    Filenames::write_unextended_leafname(NEWLEAF, base_filename);
    Str::truncate(NEWLEAF, 16);
    WRITE_TO(NEWLEAF, "-%d.html", i);
    rs.prototype_HTML_file = Filenames::in(P, NEWLEAF);
    DISCARD_TEXT(NEWLEAF)
    rs.relevant_node_ID = NULL;
    rs.first_flag = FALSE;
    rs.last_flag = FALSE;
    if (i == 1) rs.first_flag = TRUE;
    else if (i == count) rs.last_flag = TRUE;
    rs.stage = 1;
    rs.REPORT_TO = OUT;
    rs.test_case_letter = (char) (((int) 'A') + i - 1);

This code is used in §5.

§6.

void Reporter::combine_filter(text_stream *line_text, text_file_position *tfp, void *vrs) {
    report_state *rs = vrs;
    text_stream *OUT = rs->REPORT_TO;
    match_results mr = Regexp::create_mr();
    if (Regexp::match(&mr, line_text, U"<!--INTEST REPORT BEGINS-->")) rs->stage = 2;
    else if (Regexp::match(&mr, line_text, U"<!--INTEST REPORT ENDS-->")) rs->stage = 3;
    else if (((rs->stage == 1) && (rs->first_flag)) || ((rs->stage == 3) && (rs->last_flag)))
        WRITE("%S\n", line_text);
    else if (rs->stage == 2) {
        WRITE("%S\n", line_text);
    }
    Regexp::dispose_of(&mr);
}
