如何基于AST按层次顺序提取origen_testers测试名称？

Question

我们在origen_testers中使用了n个外部绑定规则引擎与使用本机绑定API的方法，并且需要按照正确的顺序传递测试名称的列表。当我们使用包含on_fail或on_pass流参数的procs时，就会出现问题。这些子测试可以包含几层类似的proc调用。子测试在父测试之前先被处理，因此二进制顺序被颠倒。是否有一种方法可以提取一组测试名称，以保留父级到子级的关系？我知道flow.atp.raw显示了层次结构。

如何按照正确的顺序选择TestSuite名称？

下面是ATP的一个例子：

s(:test,
s(:object, <TestSuite: jtag_ccra_all_vmin>),
s(:name, "jtag_ccra_all_vmin"),
s(:number, 0),
s(:id, "jtag_ccra_all_vmin"),
s(:on_fail,
  s(:if_flag, "$Alarm",
    s(:render, "multi_bin;")),
  s(:test,
    s(:object, <TestSuite: jtag_ccra_top_vmin>),
    s(:name, "jtag_ccra_top_vmin"),
    s(:number, 0),
    s(:id, "jtag_ccra_top_vmin"),
    s(:on_fail,
      s(:if_flag, "$Alarm",
        s(:render, "multi_bin;")))),
  s(:test,
    s(:object, <TestSuite: jtag_ccra_gasket_vmin>),
    s(:name, "jtag_ccra_gasket_vmin"),
    s(:number, 0),
    s(:id, "jtag_ccra_gasket_vmin"),
    s(:on_fail,

我想知道是否有办法按顺序提取姓名：

['jtag_ccra_all_vmin', 'jtag_ccra_top_vmin', 'jtag_ccra_gasket_vmin']

flow.atp.raw.children按照数组的顺序返回它们，但是我只想查询name属性和name节点对象。

thx

从AST中提取信息的方法是制作一个处理器，如下所示：https://github.com/Origen-SDK/origen_testers/blob/master/lib/origen_testers/atp/processors/extract_set_flags.rb

在您的处理器中，您将创建一个名为on_test的方法，然后从该方法中提取名称。这是未经测试的，但类似的情况如下：

class ExtractTestNames < OrigenTesters::ATP::Processor
  def run(node)
    @results = []
    process(node)
    @results
  end

  # All 'test' nodes in the AST will be handed to this method, all nodes which don't have
  # a specific handler defined will pick up a default handler which simply processes
  # (looks for a handler for) all of the node's children
  def on_test(node)
    @results << node.find(:name).value
    # Keep processing the children of this node, so that any tests embedded
    # in on_fail nodes, etc. are picked up
    process_all(node.children)
  end
end

称之为：

ExtractTestNames.new.run(flow.atp.raw)  # => ['jtag_ccra_all_vmin', 'jtag_ccra_top_vmin', ...]
