| 15 | <para>Most packages provide a test suite. Running the test suite for a
|
|---|
| 16 | newly built package is a good idea because it can provide a <quote>sanity
|
|---|
| 17 | check</quote> indicating that everything compiled correctly. A test suite
|
|---|
| 18 | that passes its set of checks usually proves that the package is
|
|---|
| 19 | functioning as the developer intended. It does not, however, guarantee
|
|---|
| 20 | that the package is totally bug free.</para>
|
|---|
| 21 |
|
|---|
| 22 | <para>Some test suites are more important than others. For example,
|
|---|
| 23 | the test suites for the core toolchain packages—GCC, Binutils, and
|
|---|
| 24 | Glibc—are of the utmost importance due to their central role in a
|
|---|
| 25 | properly functioning system. The test suites for GCC and Glibc can
|
|---|
| 26 | take a very long time to complete, especially on slower hardware, but
|
|---|
| 27 | are strongly recommended.</para>

| 30 | <para>It is not possible to run testsuites when cross-compiling, so there

|
|---|
| 35 | <para>A common issue with running the test suites for Binutils and GCC
|
|---|
| 36 | is running out of pseudo terminals (PTYs). This can result in a high
|
|---|
| 37 | number of failing tests. This may happen for several reasons, but the
|
|---|
| 38 | most likely cause is that the host system does not have the
|
|---|
| 39 | <systemitem class="filesystem">devpts</systemitem> file system set up
|
|---|
| 40 | correctly. This issue is discussed in greater detail at
|

|
|---|
| 43 | <para>Sometimes package test suites will fail, but for reasons which the
|
|---|
| 44 | developers are aware of and have deemed non-critical. Consult the logs located
|
|---|
| 45 | at <ulink url="&test-results;"/> to verify whether or not these failures are
|
|---|
| 46 | expected. This site is valid for all tests throughout this book.</para>
