# Target System We selected a Highly Configuration System active and available [online](https://gitlab.com/libssh/libssh-mirror). This system was mined on 2020-04-02. We identified 44 product variants, of which we selected 31 that have at least one failed test case in their history of builds. The first line of the table presents a set with all test cases considering every variant. The first column shows the variant name and the second columns its acronym used to improve the visualization during analysis. The third column shows the period that each variant was used. The fourth column presents the total of builds identified. Only valid builds (success or fail) were considered, that is, we discarded builds with some problem, for instance, canceled builds. The fifth column shows the total of failures found, and in parenthesis the number of builds in which at least one test failed. The sixth column shows the number of different (unique) test cases identified from build logs, and in parenthesis the range of test cases executed in the builds. The last columns present, for each system, the mean (± standard deviation) duration in minutes of the CI Cycles and the interval between them. | **Name** | **Period** | **Builds** | **Failures** | **Test Cases** | **Duration (min)** | **Interval (min)** | |-----------|-----------|-----------|-----------|-----------|-----------|-----------| |*Total* | 2018/04/12-2020/02/25 | 334 | 223 (127) | 62 (17 - 62) | 0.4029 (2.037) | 1142.528 (459.283) | | *address-sanitizer* | 2018/04/18-2018/04/18 | 1 | 13 (1) | 29 (29 - 29) | 0.0110 (0.032) | - | | *CentOS7-openssl* | 2018/04/12-2018/04/12 | 1 | 1 (1) | 17 (17 - 17) | 0.0237 (0.042) | - | | *CentOS7-openssl 1.0.x-x86-64* | 2018/04/12-2018/04/18 | 22 | 8 (7) | 29 (17 - 29) | 0.0104 (0.02) | 1320.7984 (287.806) | | *centos7-openssl_1.0.x-x86-64* | 2018/04/18-2019/12/10 | 128 | 1 (1) | 26 (17 - 25) | 0.0332 (0.1) | 972.3706 (457.855)| | *Debian.cross.mips-linux-gnu* | 2018/07/02-2018/12/24 | 131 | 7 (7) | 29 (19 - 29) | 1.3815 (4.122) | 956.783 (499.357) | | *Debian-openssl 1.0.x-aarch64* | 2018/04/12-2018/04/13 | 8 | 1 (1) | 17 (17 - 17) | 0.0431 (0.083) | 1298.6738 (306.178) | | *fedora-libgcrypt-x86_64* | 2018/09/10-2020/02/25 | 179 | 11 (11) | 57 (40 - 57) | 0.0669 (0.204) | 930.5167 (533.409) | | *fedora-mbedtls-x86-64* | 2018/06/27-2019/12/10 | 108 | 16 (6) | 40 (30 - 40) | 0.0554 (0.16) | 987.9657 (458.517) | | *fedora-mbedtls-x86_64* | 2018/09/10-2020/02/25 | 178 | 2 (2) | 56 (39 - 56) | 0.0568 (0.177) | 904.7565 (534.632) | | *Fedora-openssl* | 2018/04/12-2018/04/12 | 1 | 1 (1) | 17 (17 - 17) | 0.0149 (0.031) | - | | *Fedora-openssl 1.1.x-x86-64* | 2018/04/12-2018/04/18 | 21 | 3 (3) | 29 (17 - 29) | 0.0120 (0.027) | 1315.1925 (293.81)| | *fedora-openssl_1.1.x-x86-64* | 2018/04/18-2019/12/10 | 125 | 14 (13) | 41 (29 - 41) | 0.0489 (0.132) | 993.4781 (455.632)| | *fedora-openssl_1.1.x-x86-64-release* | 2018/08/20-2019/03/13 | 57 | 4 (4) | 41 (38 - 41) | 0.0485 (0.126) | 927.5525 (463.556)| | *fedora-openssl_1.1.x-x86_64* | 2018/09/10-2020/02/25 | 179 | 3 (3) | 60 (40 - 60) | 0.0604 (0.195) | 905.6718 (535.739)| | *fedora-openssl_1.1.x-x86_64-fips* | 2019/06/13-2020/02/25 | 71 | 11 (10) | 57 (55 - 57) | 0.0805 (0.297) | 1013.623 (538.089)| | *fedora-openssl_1.1.x-x86_64-minimal* | 2018/12/13-2020/02/25 | 124 | 1 (1) | 45 (40 - 45) | 0.0461 (0.15) | 927.5229 (534.695)| | *fedora-undefined-sanitizer* | 2018/04/18-2020/02/25 | 307 | 16 (15) | 57 (29 - 57) | 0.0701 (0.208) | 966.4755 (506.954)| | *freebsd-x86_64* | 2018/09/10-2020/02/25 | 179 | 10 (3) | 33 (24 - 33) | 0.0346 (0.102) | 886.7128 (543.546)| | *mingw32* | 2018/06/27-2019/12/10 | 86 | 3 (3) | 16 (10 - 16) | 0.0849 (0.229) | 951.7082 (482.182)| | *mingw64* | 2018/06/27-2019/12/10 | 86 | 3 (3) | 16 (10 - 16) | 0.0610 (0.142) | 957.3851 (477.583)| | *pages* | 2018/04/18-2018/04/18 | 3 | 18 (3) | 29 (29 - 29) | 0.0088 (0.022) | 1434.4083 (0.608)| | *tumbleweed-openssl_1.1.x-x86-64* | 2018/05/30-2019/12/10 | 103 | 24 (8) | 41 (29 - 41) | 0.0568 (0.15) | 963.3945 (482.27)| | *tumbleweed-openssl_1.1.x-x86-64-release* | 2018/08/20-2019/03/13 | 57 | 1 (1) | 41 (38 - 41) | 0.0600 (0.155) | 942.0249 (457.872)| | *tumbleweed-openssl_1.1.x-x86_64-clang* | 2018/09/10-2020/02/25 | 180 | 19 (10) | 57 (38 - 57) | 0.0616 (0.184) | 909.4417 (536.359)| | *tumbleweed-openssl_1.1.x-x86_64-gcc* | 2018/09/10-2020/02/25 | 176 | 16 (7) | 56 (38 - 56) | 0.0620 (0.184) | 896.6659 (536.939)| | *tumbleweed-openssl_1.1.x-x86_64-gcc7* | 2018/09/10-2020/02/25 | 179 | 15 (7) | 57 (38 - 57) | 0.0625 (0.187) | 902.7045 (540.006)| | *tumbleweed-undefined-sanitizer* | 2018/05/30-2020/02/25 | 300 | 36 (14) | 56 (29 - 56) | 0.0707 (0.196) | 956.385 (514.161)| | *ubuntu-openssl_1.1.x-x86_64* | 2019/12/23-2020/02/25 | 13 | 10 (5) | 57 (57 - 57) | 0.0583 (0.19) | 1036.3259 (543.659)| | *undefined-sanitizer* | 2018/04/18-2018/04/18 | 4 | 29 (2) | 29 (29 - 29) | 0.0162 (0.043) | 1430.6278 (1.341)| | *visualstudio-x86* | 2018/11/30-2020/02/25 | 116 | 13 (11) | 18 (16 - 18) | 0.0044 (0.007) | 953.6386 (530.41)| | *visualstudio-x86_64* | 2018/11/30-2020/02/25 | 116 | 14 (14) | 18 (16 - 18) | 0.0051 (0.01) | 957.3534 (534.557)| ## Download dataset The complete dataset is available on Dataverse.
