一、 简介
本文主要介绍postgres的测试相关功能，利用自带的测试工程和测试用例实现
二、 regress（回归测试）
首先，编译源码：
[appusr@postgre postgresql-10.5]$ export PGHOME=/home/appusr/PostgreSQL/pgsql-10
[appusr@postgre postgresql-10.5]$ ./configure --enable-rpath --prefix=$PGHOME --includedir=$PGHOME/include --mandir=$PGHOME/share/man --datadir=$PGHOME/share --with-icu --with-perl --with-python --with-tcl --with-tclconfig=/usr/lib64 --with-openssl --with-pam --with-gssapi --with-includes=/usr/include --with-libraries=/usr/lib64 --enable-nls --enable-dtrace --with-uuid=e2fs --with-libxml --with-libxslt --with-ldap --with-selinux --with-systemd --docdir=$PGHOME/doc --htmldir=$PGHOME/doc/html --enable-debug
[appusr@postgre postgresql-10.5]$ make -j4 all

All 178 tests passed. /*这里是测试结果报告汇总，一共178个测试用例，全部通过*/
=======================
make: Leaving directory `/home/appusr/pg/postgresql-10.5/src/test/regress'
解析：
sql：里面存放测试用例的SQL文件
expected：里面存放测试用例期望输出的结果
pg_regress采用psql命令执行sql文件，将本次执行结果输出到result文件夹中
然后对比result和expected的文件，结果与期望一致，则测试通过，否则测试失败。
三、 isolation （隔离测试）
首先，编译源码：
与 regress（回归测试）的测试一样
执行 isolation 测试工程代码

All 67 tests passed. /*这里是测试结果报告汇总，一共67个测试用例，全部通过*/
======================
make: Leaving directory `/home/appusr/pg/postgresql-10.5/src/test/isolation'
解析：
sql：里面存放测试用例的SQL文件
expected：里面存放测试用例期望输出的结果
pg_regress采用psql命令执行sql文件，将本次执行结果输出到result文件夹中
然后对比result和expected的文件，结果与期望一致，则测试通过，否则测试失败。
四、 modules（模块测试）
首先，编译源码：
与 regress（回归测试）的测试一样
测试的模块有：
brin ——
commit_ts —— 事务提交
dummy_seclabel ——
snapshot_too_old —— 快照太旧
test_ddl_deparse ——
test_extensions —— extension扩展模块
test_parser —— parser语法分析模块
test_pg_dump —— pg_dump
test_rls_hooks ——
test_shm_mq ——
worker_spi SPI模块 ——

每个模块下面均有：
sql：里面存放测试用例的SQL文件
expected：里面存放测试用例期望输出的结果
pg_regress采用psql命令执行sql文件，将本次执行结果输出到result文件夹中
然后对比result和expected的文件，结果与期望一致，则测试通过，否则测试失败。
五、 coverage（测试代码覆盖率）
在postgres的编译选项中，有一个特别的选项：
--enable-coverage build with coverage testing instrumentation
如果使用GCC，所有的程序和库连同代码覆盖测试设置一起被编译。 在运行时，它们与代码覆盖率度量在编译目录下生成文件。
使用的工具有gcov、lcov:
gcov:一个可用于C/C++的代码覆盖工具，是gcc的内建工具。
lcov:用来解析程序gcov的输出结果，最终输出成html格式的报告。
缺少lcov组件：源码安装
[root@postgre appusr]# wget https://jaist.dl.sourceforge.net/project/ltp/Coverage%20Analysis/LCOV-1.13/lcov-1.13.tar.gz
[root@postgre appusr]# tar -zxvf lcov-1.13.tar.gz
[root@postgre appusr]# cd lcov-1.13/
[root@postgre lcov-1.13]# make install
配置postgres编译选项
[appusr@postgre postgresql-10.5]$ export PGHOME=/home/appusr/PostgreSQL/pgsql-10
[appusr@postgre postgresql-10.5]$ ./configure --enable-rpath --prefix=$PGHOME --includedir=$PGHOME/include --mandir=$PGHOME/share/man --datadir=$PGHOME/share --with-icu --with-perl --with-python --with-tcl --with-tclconfig=/usr/lib64 --with-openssl --with-pam --with-gssapi --with-includes=/usr/include --with-libraries=/usr/lib64 --enable-nls --enable-dtrace --with-uuid=e2fs --with-libxml --with-libxslt --with-ldap --with-selinux --with-systemd --docdir=$PGHOME/doc --htmldir=$PGHOME/doc/html --enable-debug --enable-coverage
[appusr@postgre postgresql-10.5]$ make
测试代码覆盖率，并输出报告

利用 valgrind 来进行内存检测
gprof 和 oprofile 进行性能分析
