}可以通过 node ./tests/test.app.js 命令来测试查询：
➜ nodejs git:(v2.0-for-nodejs) ✗ node ./tests/test.app.js --help
usage: Usage node test.app.js <agrs>
ip2region test app
optional arguments:
-h, --help show this help message and exit
-d DB, --db DB ip2region binary xdb file path, default: ../../data/ip2region.xdb
-c CACHE_POLICY, --cache-policy CACHE_POLICY
cache policy: file/vectorIndex/content, default: content例如：使用默认的 data/ip2region.xdb 文件进行查询测试：
➜ nodejs git:(v2.0-for-nodejs) ✗ node ./tests/test.app.js
parameters:
dbPath: ../../data/ip2region.xdb
cache-policy: content
type 'quit' to exit
ip2region>> 1.2.3.4
{ region: '美国|0|华盛顿|0|谷歌', ioCount: 0, took: 54.606261 }
ip2region>>输入 ip 即可进行查询测试，也可以分别设置 cache-policy 为 file/vectorIndex/content 来测试三种不同缓存实现的查询效果。
➜ nodejs git:(v2.0-for-nodejs) ✗ node ./tests/bench.app.js --help
usage: Usage node test.app.js [command options]
ip2region benchmark app
optional arguments:
-h, --help show this help message and exit
--db DB ip2region binary xdb file path, default: ../../data/ip2region.xdb
--src SRC source ip text file path, default: ../../data/ip.merge.txt
--cache-policy CACHE_POLICY
cache policy: file/vectorIndex/content, default: content
例如：通过默认的 data/ip2region.xdb 和 data/ip.merge.txt 文件进行 bench 测试：
➜ nodejs git:(v2.0-for-nodejs) ✗ node ./tests/bench.app.js
options:
dbPath: ../../data/ip2region.xdb
src: ../../data/ip2region.xdb
cache-policy: content
Bench finished, {cachePolicy: content, total: 3417955, took: 20.591887765s, cost: 6.02462225658325μs/op}可以通过分别设置 cache-policy 为 file/vectorIndex/content 来测试三种不同缓存实现的效果。
Note: 注意 bench 使用的 src 文件要是生成对应 xdb 文件相同的源文件。
