|
|---|
| 12 |
|
|---|
| 13 | <para>Most packages provide a test suite. Running the test suite for a
|
|---|
| 14 | newly built package is a good idea because it can provide a <quote>sanity
|
|---|
| 15 | check</quote> indicating that everything compiled correctly. A test suite
|
|---|
| 16 | that passes its set of checks usually proves that the package is
|
|---|
| 17 | functioning as the developer intended. It does not, however, guarantee
|
|---|
| 18 | that the package is totally bug free.</para>
|
|---|
| 19 |
|
|---|
| 20 | <para>Some test suites are more important than others. For example,
|
|---|
| [ee714d3] | 21 | the test suites for the core toolchain packages—GCC, binutils, and
|
|---|
| 22 | glibc—are of the utmost importance due to their central role in a
|
|---|
| 23 | properly functioning system. The test suites for GCC and glibc can
|
|---|
| [6a3b6af] | 24 | take a very long time to complete, especially on slower hardware, but
|
|---|
| 25 | are strongly recommended.</para>

|---|
| [ee714d3] | 28 | <para>Running the test suites in <xref linkend="chapter-cross-tools"/>
|
|---|
| 29 | and <xref linkend="chapter-temporary-tools"/>
|
|---|
| [efcb393] | 30 | is impossible, since the programs are compiled with a cross-compiler,
|
|---|
| 31 | so are not supposed to be able to run on the build host.</para>

|

| 33 |
|
|---|
| [ee714d3] | 34 | <para>A common issue with running the test suites for binutils and GCC
|
|---|
| [6a3b6af] | 35 | is running out of pseudo terminals (PTYs). This can result in a high
|
|---|
| 36 | number of failing tests. This may happen for several reasons, but the
|
|---|
| 37 | most likely cause is that the host system does not have the
|
|---|
| 38 | <systemitem class="filesystem">devpts</systemitem> file system set up
|
|---|
| [fe6ca49] | 39 | correctly. This issue is discussed in greater detail at
|
|---|

|
|---|
| [6a3b6af] | 41 |
|
|---|
| 42 | <para>Sometimes package test suites will fail, but for reasons which the
|
|---|
| 43 | developers are aware of and have deemed non-critical. Consult the logs located
|
|---|
| 44 | at <ulink url="&test-results;"/> to verify whether or not these failures are
|
|---|
| 45 | expected. This site is valid for all tests throughout this book.</para>
